WEBVTT 1 00:00:00.480 --> 00:00:03.780 Matthew Bellis: And we are recording now it's all you. 2 00:00:05.940 --> 00:00:07.290 Edgar Fernando Carrera Jarrin: Alright, thanks. 3 00:00:09.360 --> 00:00:12.960 Edgar Fernando Carrera Jarrin: Okay let's let's just start with the analysis slow lesson. 4 00:00:15.690 --> 00:00:25.830 Edgar Fernando Carrera Jarrin: Remember, you, you had a preparatory work so here's the first one, I hope you can see my I guess you can see everything right i'm going to switch back and forth between my. 5 00:00:27.120 --> 00:00:49.500 Edgar Fernando Carrera Jarrin: My terminal and the instructions of the instructions, I have them in my own in my other monitor, so I can copy of the commands while I do this demonstration this sign that keeps popping up about this person who could we couldn't have met for some reason it's really. 6 00:00:50.970 --> 00:00:52.770 Edgar Fernando Carrera Jarrin: getting a little bit tonight okay. 7 00:00:54.030 --> 00:00:54.990 Edgar Fernando Carrera Jarrin: So. 8 00:00:56.010 --> 00:01:07.590 Edgar Fernando Carrera Jarrin: there's one one activity in the prep work that was really important, so please raise your hand if you you've completed it and what I referred to is the need to have the files copied locally. 9 00:01:08.220 --> 00:01:21.450 Edgar Fernando Carrera Jarrin: In your machine, I mean we could work in some other way i'll show you, but if you can, please, please do this because we're going to need this bias. 10 00:01:22.620 --> 00:01:25.410 Edgar Fernando Carrera Jarrin: For to work in the hands on session. 11 00:01:28.560 --> 00:01:30.600 Edgar Fernando Carrera Jarrin: So you can see that many hands. 12 00:01:35.280 --> 00:01:48.630 Edgar Fernando Carrera Jarrin: So is this, because you didn't do it, or because you are not going to do it, or because there were some problem you can turn on your microphone if you, if you like, it's it's okay. 13 00:01:58.620 --> 00:02:06.180 Edgar Fernando Carrera Jarrin: Okay, if you haven't if you didn't have the chance to do it, please do it like in the break TV if you, if you like. 14 00:02:08.070 --> 00:02:11.040 Edgar Fernando Carrera Jarrin: Because yeah we're going to need these files. 15 00:02:12.090 --> 00:02:13.560 Edgar Fernando Carrera Jarrin: So i'm going to jump to the next. 16 00:02:15.510 --> 00:02:32.760 Edgar Fernando Carrera Jarrin: episode Okay, so this is the the episode for today, this is the demonstration, so a principal you're welcome to follow along but it's not required for this particular demonstration is, it is just administration okay so that's. 17 00:02:33.780 --> 00:02:38.670 Edgar Fernando Carrera Jarrin: that's fine if you if you don't want to type in like crazy. 18 00:02:40.710 --> 00:02:41.400 Edgar Fernando Carrera Jarrin: that's okay. 19 00:02:44.550 --> 00:02:49.020 Edgar Fernando Carrera Jarrin: But they will this will get you introduced to what we're doing for the next session so okay. 20 00:02:49.800 --> 00:03:02.550 Edgar Fernando Carrera Jarrin: So let's go through the overview, I had asked you and and I guess you were going through through with with Julie as well about the a is hicks did our analysis right. 21 00:03:03.090 --> 00:03:09.450 Edgar Fernando Carrera Jarrin: So it turns out that the higgs to tau tau analysis is already implemented in this very simplified way. 22 00:03:09.960 --> 00:03:30.720 Edgar Fernando Carrera Jarrin: It the code for this lives into repositories it is all explained here, if you want to come back to this image here, and these two to dunaway of the outreach to the within using for these demonstrations and these hicks it out our analysis repository so in the first one. 23 00:03:34.110 --> 00:03:43.380 Edgar Fernando Carrera Jarrin: What happens is that you skim the data, you know you have all these data sets that you want to pull out the basic information for your analysis. 24 00:03:43.830 --> 00:04:01.980 Edgar Fernando Carrera Jarrin: Because they are very large data sets and so that's done in the first part and in the second part you, you really performed analysis and maker subplots so this lesson is really about trying to do the same thing, but in a even more simple way. 25 00:04:03.210 --> 00:04:15.180 Edgar Fernando Carrera Jarrin: If you went through this code skim through or something you may have noticed that they use the our data frame class from route, which is an implementation that allows you to do. 26 00:04:15.720 --> 00:04:25.410 Edgar Fernando Carrera Jarrin: columnar analysis, rather than row analysis you don't go event by event but you go kind of like the whole matrix of events. 27 00:04:27.000 --> 00:04:33.360 Edgar Fernando Carrera Jarrin: Alright, so here here's my little my little cartoon about what we're planning to do today, I even. 28 00:04:34.620 --> 00:04:43.680 Edgar Fernando Carrera Jarrin: pay attention to be to the colors which the match right the colors of our workshop so essentially we're gonna. 29 00:04:44.490 --> 00:04:59.910 Edgar Fernando Carrera Jarrin: What we like to do is to pull out some interesting information from our data sets the open data sets from cms and we're going to pass it through through the poet is kaymer Okay, so you already saw this. 30 00:05:00.960 --> 00:05:13.200 Edgar Fernando Carrera Jarrin: We could we could filter this, for example by the trigger or imposing certain parts of the physical objects and then we're gonna end up with another route file. 31 00:05:14.850 --> 00:05:24.090 Edgar Fernando Carrera Jarrin: But this route file is not as complicated complicated, as the first one is a flat and to boil It really is just a bunch of variables and stored in the fat weight. 32 00:05:24.660 --> 00:05:37.050 Edgar Fernando Carrera Jarrin: And then we're going to analyze those variables in order to make some pretty plots and in the process we're going to have another route file with a middle histogram saying. 33 00:05:38.430 --> 00:05:45.090 Edgar Fernando Carrera Jarrin: Alright, so we're going to do, essentially all what is in this blue part and. 34 00:05:46.200 --> 00:06:08.490 Edgar Fernando Carrera Jarrin: Especially for the first step we're not going to be able to do everything, because there are so many files in our data set and is quite large so we may need to do or use some computing some cloud resources in order to do this okay and we'll we'll see that today or tomorrow. 35 00:06:10.410 --> 00:06:16.890 Edgar Fernando Carrera Jarrin: You know about this already the data sets that we are interested in are these. 36 00:06:17.640 --> 00:06:31.800 Edgar Fernando Carrera Jarrin: So for the collisions for the real data medical issues that happened in the machine, we are using the run 2012 essentially data for a topless X data set. 37 00:06:32.670 --> 00:06:38.490 Edgar Fernando Carrera Jarrin: And we need to consider our background, yes, you went through this with Julie. 38 00:06:39.090 --> 00:06:48.840 Edgar Fernando Carrera Jarrin: Yesterday, and we have a drill yams right to especially to TAO towers, but it's essentially to leptons you have to the bar now the bliss jets. 39 00:06:49.290 --> 00:07:01.500 Edgar Fernando Carrera Jarrin: And also, you want to compare this with the with the signal that you expect to obtain, and so we have two types of mechanisms for his production and you also went through this. 40 00:07:03.480 --> 00:07:09.420 Edgar Fernando Carrera Jarrin: you're ready kind of selected the trigger remember you're asking for a new one and in. 41 00:07:10.470 --> 00:07:11.190 Edgar Fernando Carrera Jarrin: An atari. 42 00:07:12.630 --> 00:07:17.100 Edgar Fernando Carrera Jarrin: Alright, so this is, this is what it's done and also in the original simplified analysis. 43 00:07:18.120 --> 00:07:22.320 Edgar Fernando Carrera Jarrin: Now, and let's try to think about this. 44 00:07:23.970 --> 00:07:37.320 Edgar Fernando Carrera Jarrin: Other little bit more carefully imagine if you're doing this analysis by yourself and you have to make all the simulations, then you need to know how many events you need to simulate because this. 45 00:07:38.430 --> 00:07:57.750 Edgar Fernando Carrera Jarrin: requires computing power, and you know that's not always available or cheap and so you want to do the most efficient production and in order to know how many events you, you want to simulate you need to do a calculation for the luminosity of your data. 46 00:07:59.520 --> 00:08:04.500 Edgar Fernando Carrera Jarrin: How many inverse that the barns or how many inverse bigger barns of data, you have. 47 00:08:05.970 --> 00:08:12.270 Edgar Fernando Carrera Jarrin: Alright, so, and the first demonstration, I will show you how to calculate this using our tools. 48 00:08:14.370 --> 00:08:31.530 Edgar Fernando Carrera Jarrin: We have fortunately when guide in the CERN open data portal, which is here i'm not open this that shows you and guides you through the calculation of this luminosity variables Okay, you can read this later, but I just trans. 49 00:08:34.200 --> 00:08:43.350 Edgar Fernando Carrera Jarrin: copy some of these instructions here right, the most important they're the ones that we need to execute in order to get our numbers. 50 00:08:44.490 --> 00:08:50.190 Edgar Fernando Carrera Jarrin: So i'm going to start with a docker container actually i'm going to start with a fresh container. 51 00:08:51.750 --> 00:08:53.940 Edgar Fernando Carrera Jarrin: Here okay and. 52 00:08:56.010 --> 00:08:56.880 Edgar Fernando Carrera Jarrin: let's see. 53 00:08:58.080 --> 00:09:01.440 Edgar Fernando Carrera Jarrin: It should be here Okay, this is my fresh container. 54 00:09:02.460 --> 00:09:02.910 Edgar Fernando Carrera Jarrin: Okay. 55 00:09:05.250 --> 00:09:07.950 Edgar Fernando Carrera Jarrin: let's see if I can exit. 56 00:09:10.260 --> 00:09:15.540 Edgar Fernando Carrera Jarrin: So I can do docker, by the way, is this a good size for the. 57 00:09:16.710 --> 00:09:17.760 Edgar Fernando Carrera Jarrin: For the letters. 58 00:09:19.680 --> 00:09:21.000 Edgar Fernando Carrera Jarrin: I don't know if it's too small. 59 00:09:25.110 --> 00:09:30.150 Matthew Bellis: there's a couple of thumbs up in the in the chat so it looks like at least some people left that works for them. 60 00:09:34.200 --> 00:09:36.630 Edgar Fernando Carrera Jarrin: Okay, I made a mistake of trying to. 61 00:09:39.090 --> 00:09:42.180 Edgar Fernando Carrera Jarrin: trying to find another one here but let's see. 62 00:09:48.780 --> 00:09:49.410 This. 63 00:09:51.360 --> 00:09:52.980 Edgar Fernando Carrera Jarrin: problem with that is. 64 00:09:54.060 --> 00:10:06.660 Edgar Fernando Carrera Jarrin: yeah so I created a fresh fresh container and I called it my analysis slow or short for that so that's what i'm going to use okay so i'm gonna do Dr starts. 65 00:10:08.490 --> 00:10:09.180 Edgar Fernando Carrera Jarrin: My. 66 00:10:10.590 --> 00:10:14.520 Edgar Fernando Carrera Jarrin: slow and that will put me in my fresh container. 67 00:10:18.570 --> 00:10:22.500 Edgar Fernando Carrera Jarrin: So I don't have anything right at the at the home directory. 68 00:10:25.170 --> 00:10:26.790 Edgar Fernando Carrera Jarrin: And the source right but. 69 00:10:29.070 --> 00:10:31.320 Edgar Fernando Carrera Jarrin: switch to my instructions here. 70 00:10:37.140 --> 00:10:44.160 Edgar Fernando Carrera Jarrin: Okay, so what I like to do is to go to the to the home area, so I don't pollute the. 71 00:10:46.380 --> 00:10:58.410 Edgar Fernando Carrera Jarrin: The source area of our cms is w installation and here i'm gonna just install this a tool that we have in cms which is called. 72 00:10:58.920 --> 00:11:13.530 Edgar Fernando Carrera Jarrin: Braille coc all right, and if you go through the instructions, it will ask you to download this file and you can easily run the installer with this line, but here, instead of local real. 73 00:11:14.790 --> 00:11:19.740 Edgar Fernando Carrera Jarrin: candidates, we have to drill a condom okay. 74 00:11:21.120 --> 00:11:21.840 Edgar Fernando Carrera Jarrin: and 75 00:11:24.540 --> 00:11:25.500 What happened. 76 00:11:27.270 --> 00:11:46.470 Edgar Fernando Carrera Jarrin: Oh yeah so sometimes sometimes when you're trying to access these sites in at CERN you have to use the no certificate sign and I forgot to put this in the instructions, but actually is, in our. 77 00:11:48.540 --> 00:11:55.440 Edgar Fernando Carrera Jarrin: guide here, so this is the switch i'm forgetting in my w get. 78 00:12:01.020 --> 00:12:02.130 My mouse is. 79 00:12:03.780 --> 00:12:04.830 Edgar Fernando Carrera Jarrin: Giving the trouble here. 80 00:12:14.430 --> 00:12:15.150 Edgar Fernando Carrera Jarrin: In there. 81 00:12:57.090 --> 00:13:03.300 Edgar Fernando Carrera Jarrin: Finding this way everything works when you test it but. 82 00:13:04.980 --> 00:13:05.970 Edgar Fernando Carrera Jarrin: it's not found. 83 00:13:07.500 --> 00:13:07.890 Yet. 84 00:13:33.000 --> 00:13:33.540 Edgar Fernando Carrera Jarrin: I must have. 85 00:13:37.050 --> 00:13:42.480 Edgar Fernando Carrera Jarrin: Their own line in my own instructions, but the instructions from the official guide work. 86 00:13:43.530 --> 00:13:45.720 Edgar Fernando Carrera Jarrin: So it's taking a little bit of time. 87 00:13:46.800 --> 00:13:50.340 Edgar Fernando Carrera Jarrin: To to probably copy is over ready any case. 88 00:13:53.580 --> 00:13:56.910 Edgar Fernando Carrera Jarrin: This is where you have to do right and just install it. 89 00:13:58.650 --> 00:14:04.920 Edgar Fernando Carrera Jarrin: And then you go through all those steps you have to put it in your path and install it with. 90 00:14:06.420 --> 00:14:10.620 Edgar Fernando Carrera Jarrin: With tip and then you have this executable code Braille car. 91 00:14:11.820 --> 00:14:17.580 Edgar Fernando Carrera Jarrin: And in this guy they're all the instructions of the different things, you can do with this tool. 92 00:14:19.230 --> 00:14:26.760 Edgar Fernando Carrera Jarrin: But what we would like to do is to execute the luminosity calculation and that's what I tried to show here. 93 00:14:27.900 --> 00:14:28.170 Okay. 94 00:14:33.060 --> 00:14:33.540 Edgar Fernando Carrera Jarrin: Yes. 95 00:14:37.140 --> 00:14:40.890 Jiri Chudoba: What was the correct address to download this bill condon. 96 00:14:42.480 --> 00:14:43.590 Edgar Fernando Carrera Jarrin: yeah sorry yeah. 97 00:14:48.300 --> 00:14:49.020 Edgar Fernando Carrera Jarrin: say again. 98 00:14:50.880 --> 00:14:51.450 Jiri Chudoba: to chair. 99 00:14:52.740 --> 00:14:53.100 chair. 100 00:14:54.330 --> 00:14:54.600 Jiri Chudoba: and 101 00:15:01.230 --> 00:15:08.250 Edgar Fernando Carrera Jarrin: it's just my mouse that is acting up to compare oh yeah I am yeah. 102 00:15:10.170 --> 00:15:20.520 Edgar Fernando Carrera Jarrin: I see this one has here 1.1 Point seven and I was in 3.0 point zero because that's the one that I use you're showing me Alex plus I was, I was making them as. 103 00:15:21.930 --> 00:15:22.770 Jiri Chudoba: We go through the. 104 00:15:23.820 --> 00:15:25.230 Jiri Chudoba: dark or. 105 00:15:27.180 --> 00:15:27.390 Jiri Chudoba: light. 106 00:15:29.520 --> 00:15:29.790 yeah. 107 00:15:31.950 --> 00:15:39.210 Edgar Fernando Carrera Jarrin: Okay, so yeah which I should correct that anyway that's that's done right and. 108 00:15:40.350 --> 00:15:41.490 You see me Hello. 109 00:15:42.630 --> 00:16:08.640 Edgar Fernando Carrera Jarrin: Yes, just a clarification question, so it is mandatory to get this world is in a docker but just not just to be just to be not polluting your cms software source repository you put it inside outside of this right. 110 00:16:10.050 --> 00:16:13.320 Edgar Fernando Carrera Jarrin: yeah yes, I just went to my home area. 111 00:16:14.700 --> 00:16:21.840 Edgar Fernando Carrera Jarrin: In my home area just because I don't want to have files there, but you could do it from inside I don't think it's a problem. 112 00:16:25.260 --> 00:16:27.150 Edgar Fernando Carrera Jarrin: Alright, so now, I will. 113 00:16:29.070 --> 00:16:30.390 Edgar Fernando Carrera Jarrin: I will execute this. 114 00:16:44.550 --> 00:16:56.190 Edgar Fernando Carrera Jarrin: You can notice that I made a mistake, because I have here this i'm trying to install this 1.1 point 747, and here I have 3.0 point zero. 115 00:16:57.210 --> 00:16:59.100 Edgar Fernando Carrera Jarrin: You know that that's just a mistake. 116 00:17:00.660 --> 00:17:02.190 Edgar Fernando Carrera Jarrin: Okay it's installing. 117 00:17:10.290 --> 00:17:16.620 Edgar Fernando Carrera Jarrin: Okay, so until that that is done, let me talk about this luminosity. 118 00:17:18.390 --> 00:17:29.010 Edgar Fernando Carrera Jarrin: Data quality files that we have at cms so as you can see here the next thing I will do is to download these files. 119 00:17:29.340 --> 00:17:39.330 Edgar Fernando Carrera Jarrin: So the point is that each of the data sets if you if you go to this one, for instance, the one that we're going to use they come with this file. 120 00:17:39.930 --> 00:17:50.940 Edgar Fernando Carrera Jarrin: which has a collection or a list of all the validator runs and the luminosity sections that are valid, so we exclude here, essentially in this file or with this file. 121 00:17:51.330 --> 00:18:08.460 Edgar Fernando Carrera Jarrin: exclude all those events that had some problem with the detector there were some issue with that Okay, so we need this in order to calculate our luminosity because we're going to exclude those sections that are not good. 122 00:18:09.840 --> 00:18:28.410 Edgar Fernando Carrera Jarrin: And if you look at this file, you see, you will see something like this, so here's the run and here's the set of the limit sections that are good, and you have a bunch of them, of course, alright, so we need that for our terminology calculation this thing is going is low. 123 00:18:29.880 --> 00:18:41.430 Edgar Fernando Carrera Jarrin: And then, what we will do is to just execute this command, which is the Braille God, we will ask us, we will ask it to give us the luminosity we are interfacing this. 124 00:18:42.960 --> 00:18:52.410 Edgar Fernando Carrera Jarrin: server via web, so we don't bother people at cms and in cms we have different types of libby numbers that. 125 00:18:53.250 --> 00:19:14.700 Edgar Fernando Carrera Jarrin: measure this luminosity and for run one, it is the recommendation to use the pixel let me number, and we can use different units, we will ask it to deliver the luminosity in Emperor speaker barn and notice that, for this data data sets. 126 00:19:16.200 --> 00:19:33.690 Edgar Fernando Carrera Jarrin: You have run ranges right you don't have all the runs in this beta this data sets because this is the part B of the data set so it goes from this run number two is run number so that's why you have to put the the range here, which I have done, and then. 127 00:19:34.740 --> 00:19:52.020 Edgar Fernando Carrera Jarrin: We use the quality file, because you you don't want to take into account those luminosity sections which were bad and then i'm just dumping this into into a file okay that's what I was planning to do it, but maybe the time is not my my friend. 128 00:19:53.490 --> 00:19:56.610 Edgar Fernando Carrera Jarrin: Okay let's see what we can do this thing. 129 00:19:58.410 --> 00:20:06.240 Edgar Fernando Carrera Jarrin: So the next thing I had to do is this Okay, and then we'll. 130 00:20:07.260 --> 00:20:10.080 Edgar Fernando Carrera Jarrin: In all these grill work suit. 131 00:20:11.280 --> 00:20:15.630 Edgar Fernando Carrera Jarrin: So this comes thanks to our friends in the Braille group, by the way, will shape the long. 132 00:20:19.590 --> 00:20:20.490 And he's. 133 00:20:22.500 --> 00:20:34.980 Edgar Fernando Carrera Jarrin: very sure to check that we installed correctly yes it's version 366 so that's good, and then we get our file for the quality luminosity sections. 134 00:20:36.750 --> 00:20:49.560 Edgar Fernando Carrera Jarrin: That went OK, and then we can take a look, if you wish yeah it's it's just a bunch of numbers, but you know now what they mean it's just run and the luminosity sections that are good within that run. 135 00:20:50.790 --> 00:20:58.440 Edgar Fernando Carrera Jarrin: And then we just run this command and dump everything to our looming log file that we can read later. 136 00:21:00.180 --> 00:21:05.100 Edgar Fernando Carrera Jarrin: And yeah once it's ready, we can catch this fire. 137 00:22:00.810 --> 00:22:04.380 Edgar Fernando Carrera Jarrin: This is going to take too long, we really have to. 138 00:22:06.120 --> 00:22:06.990 battle here. 139 00:22:21.000 --> 00:22:27.150 Edgar Fernando Carrera Jarrin: hey I didn't manage to dump it into a text file, but you could do that with more time I don't know what's going wrong. 140 00:22:27.780 --> 00:22:37.620 Edgar Fernando Carrera Jarrin: You know, it is really annoying that the docker containers one one feature that I don't like is this going out of bounds and then everything gets mixed up in the. 141 00:22:38.370 --> 00:22:48.900 Edgar Fernando Carrera Jarrin: In the command line I think Cecilia suggested a fixed, but the problem is that I couldn't find that package resize in the repositories of this of this. 142 00:22:50.370 --> 00:22:55.560 Edgar Fernando Carrera Jarrin: releases anyway, if someone finds a fix for that. 143 00:22:57.210 --> 00:22:59.100 We would appreciate it. 144 00:23:00.630 --> 00:23:09.930 Edgar Fernando Carrera Jarrin: Alright, so at the end of the day, right at the end of the day, what you will get is a is an output and you will get the total recorded luminosity here. 145 00:23:10.380 --> 00:23:21.930 Edgar Fernando Carrera Jarrin: So, remember that the LG has gotten continuously colliding and the detector sometimes have problems that's why you have this delivered, which corresponds to the luminosity delivered by the machine. 146 00:23:22.350 --> 00:23:31.950 Edgar Fernando Carrera Jarrin: And we take a very large fraction of that luminosity but not all, and some of those let me sexual surely empty. 147 00:23:33.360 --> 00:23:48.120 Edgar Fernando Carrera Jarrin: Are here the bottom so here's a little notes alerting you that if you get these ones, this means that they just were empty and they were they don't have any events okay so that's that's the luminosity section. 148 00:23:49.680 --> 00:23:52.680 Edgar Fernando Carrera Jarrin: The luminosity calculation for data set. 149 00:23:53.730 --> 00:23:54.960 Edgar Fernando Carrera Jarrin: Which is very important because. 150 00:23:57.270 --> 00:24:00.870 Edgar Fernando Carrera Jarrin: At some point we will have to normalize our Monaco data sets. 151 00:24:01.350 --> 00:24:13.710 Edgar Fernando Carrera Jarrin: Right, and you know how to do this at the number of respect of events that you expect of a process, you can calculate it multiplying the luminosity they integrated luminosity of with that we just estimated or. 152 00:24:14.190 --> 00:24:31.110 Edgar Fernando Carrera Jarrin: obtained and the Cross section of this process, and this is how you do it, and so, in order to to normalize your data set, you will need a scaling factor like this Okay, and so this is quite important, because otherwise your. 153 00:24:32.370 --> 00:24:42.930 Edgar Fernando Carrera Jarrin: Your analysis is not going to work out Okay, this is that down, you know it's very large, there are some terminology sections that were actually empty and so. 154 00:24:44.550 --> 00:24:50.910 Edgar Fernando Carrera Jarrin: Okay, so that's the first part of this demonstration at the second part is about this came in. 155 00:24:52.050 --> 00:25:08.310 Edgar Fernando Carrera Jarrin: So, remember that we are performing this analysis in two steps The first one is the skimmer right we these are large jobs actually or many jobs that with intention of. 156 00:25:09.390 --> 00:25:32.550 Edgar Fernando Carrera Jarrin: Taking information out from these data sets and put them in a new route file or it doesn't really have to be a route file, it could be, I don't know, an html5 file, or even a csv file, if you like, whatever for my one, but we are familiar with route so you're screwed I mean we. 157 00:25:34.350 --> 00:25:36.480 Edgar Fernando Carrera Jarrin: You have to you have to use with us. 158 00:25:37.800 --> 00:25:39.930 Edgar Fernando Carrera Jarrin: Okay, so let's let's go to. 159 00:25:40.980 --> 00:26:00.360 Edgar Fernando Carrera Jarrin: let's go to that and the key aspect here is that we're going to use what you have been using, which is the the poet package Okay, so I have a clean setup here so i'm going to go to my cms is w area I don't have anything to so i'm going to close close this from scratch. 160 00:26:02.790 --> 00:26:09.060 Edgar Fernando Carrera Jarrin: To make sure I get all of the modifications that probably were made for this workshop. 161 00:26:10.260 --> 00:26:17.340 Edgar Fernando Carrera Jarrin: And then i'm going to CD to the famous basics of the instructor, which is the the heart of this poet. 162 00:26:19.830 --> 00:26:30.780 Edgar Fernando Carrera Jarrin: And let's take a quick look at the poet configuration once again so i'm going to try that now, since I didn't have time to install here another. 163 00:26:41.040 --> 00:26:41.730 Edgar Fernando Carrera Jarrin: caller here. 164 00:26:45.450 --> 00:26:45.780 Okay. 165 00:26:47.220 --> 00:26:50.610 Edgar Fernando Carrera Jarrin: Right, so you went through all these different sections. 166 00:26:52.290 --> 00:26:53.940 Edgar Fernando Carrera Jarrin: I suppose and. 167 00:26:55.230 --> 00:26:57.990 Edgar Fernando Carrera Jarrin: The one thing that I, like you to pay attention to. 168 00:26:59.190 --> 00:27:01.230 Edgar Fernando Carrera Jarrin: Is the. 169 00:27:09.270 --> 00:27:14.010 Edgar Fernando Carrera Jarrin: Is the the source file, so you know what I think. 170 00:27:15.120 --> 00:27:19.560 Edgar Fernando Carrera Jarrin: don't take too long to install emacs here or something that has color. 171 00:27:21.870 --> 00:27:24.060 Edgar Fernando Carrera Jarrin: I think I know how to do this. 172 00:27:26.100 --> 00:27:28.620 Edgar Fernando Carrera Jarrin: Just a second i'm going to try to color is this thing. 173 00:27:37.350 --> 00:27:38.940 Edgar Fernando Carrera Jarrin: Because otherwise it's. 174 00:27:43.170 --> 00:27:45.240 Edgar Fernando Carrera Jarrin: hard to choose. 175 00:27:50.490 --> 00:27:51.270 This one. 176 00:27:59.790 --> 00:28:01.560 Edgar Fernando Carrera Jarrin: yeah if I execute this line. 177 00:28:02.730 --> 00:28:05.730 Edgar Fernando Carrera Jarrin: I should be able to see in my nano. 178 00:28:19.020 --> 00:28:20.400 Edgar Fernando Carrera Jarrin: Okay that's much better. 179 00:28:27.750 --> 00:28:28.320 Chokri Ben Romdhane: Can you. 180 00:28:28.350 --> 00:28:31.410 Edgar Fernando Carrera Jarrin: Can you turn off your microphone i'm here myself it's quite annoying. 181 00:28:34.290 --> 00:28:35.130 Edgar Fernando Carrera Jarrin: All right, thank you. 182 00:28:36.210 --> 00:28:36.870 Edgar Fernando Carrera Jarrin: So. 183 00:28:37.710 --> 00:28:39.960 Edgar Fernando Carrera Jarrin: So, the one thing that i'd like to to to say. 184 00:28:39.990 --> 00:28:40.560 Is that. 185 00:28:45.000 --> 00:28:45.240 Edgar Fernando Carrera Jarrin: If you. 186 00:28:45.900 --> 00:28:47.730 Edgar Fernando Carrera Jarrin: keep hearing myself I don't know why. 187 00:28:49.830 --> 00:28:50.280 Matthew Bellis: I think. 188 00:28:50.760 --> 00:28:52.110 You might be unmuted. 189 00:28:55.320 --> 00:28:57.120 Matthew Bellis: Thank Thank you very much thank you. 190 00:28:59.370 --> 00:29:00.000 Edgar Fernando Carrera Jarrin: yeah Thank you. 191 00:29:01.020 --> 00:29:01.770 Edgar Fernando Carrera Jarrin: yeah so. 192 00:29:03.180 --> 00:29:11.910 Edgar Fernando Carrera Jarrin: So if you want to go through all the files in the data said, you know going file by file is not the best, the best way possible, you see here. 193 00:29:13.140 --> 00:29:17.490 Edgar Fernando Carrera Jarrin: You have this source, the source, where you. 194 00:29:17.520 --> 00:29:31.230 Edgar Fernando Carrera Jarrin: input files and you have this data or or not, so you can run on data or simulation, but this is probably another way to to go if you want to process all the all the files into beta set. 195 00:29:31.860 --> 00:29:43.020 Edgar Fernando Carrera Jarrin: But here, you have an alternative to to run okay So the first thing that i'm going to try, just to test is how about if we comment this out the whole section. 196 00:29:44.940 --> 00:29:45.330 Edgar Fernando Carrera Jarrin: Okay. 197 00:29:45.780 --> 00:29:46.410 Edgar Fernando Carrera Jarrin: And then. 198 00:29:49.920 --> 00:29:52.650 Edgar Fernando Carrera Jarrin: uncommon this section, where you. 199 00:29:52.770 --> 00:29:58.080 Edgar Fernando Carrera Jarrin: are using you will be using the file you deals. 200 00:30:00.090 --> 00:30:03.240 Edgar Fernando Carrera Jarrin: From the from the framework from cms sw. 201 00:30:04.290 --> 00:30:11.160 Edgar Fernando Carrera Jarrin: And what you can see here is that you are actually loading the all the index files that you can. 202 00:30:12.420 --> 00:30:13.920 Edgar Fernando Carrera Jarrin: You can get from. 203 00:30:15.930 --> 00:30:17.130 Edgar Fernando Carrera Jarrin: From the data set. 204 00:30:18.900 --> 00:30:26.640 Edgar Fernando Carrera Jarrin: site Okay, so all these data sets have below they have all these index files, where the road files are. 205 00:30:26.970 --> 00:30:45.570 Edgar Fernando Carrera Jarrin: And instead of downloading or accessing each route file individually, you can use this functionality to just load, the text files and they will do that for you okay so take into account that these data sets are huge, so this one in particular is 11. 206 00:30:45.570 --> 00:30:46.200 Edgar Fernando Carrera Jarrin: terabytes. 207 00:30:46.980 --> 00:30:56.850 Edgar Fernando Carrera Jarrin: You know, take you up to a month or so to process, all of them in a single computer perhaps so that's probably not a good idea, but there is a way to do it okay. 208 00:30:58.650 --> 00:30:59.220 Edgar Fernando Carrera Jarrin: and 209 00:31:00.420 --> 00:31:07.740 Edgar Fernando Carrera Jarrin: Right and the rest of the stuff I guess you're ready so notice that we also have this section here, where we. 210 00:31:09.030 --> 00:31:25.140 Edgar Fernando Carrera Jarrin: actually consider this file with all our loomis sections that we're blessed that were declared good, so we are not taking into account any trouble the midsection any thing that was flagged as as having some issues. 211 00:31:27.450 --> 00:31:33.990 Edgar Fernando Carrera Jarrin: Okay, so you went through all these different objects with Julie, of the last couple of days. 212 00:31:36.300 --> 00:31:40.110 Edgar Fernando Carrera Jarrin: All right, and and here we should, in principle, change. 213 00:31:41.910 --> 00:31:56.880 Edgar Fernando Carrera Jarrin: The the right the triggers to the trigger that we want right, so we should change this line, perhaps to the just one trigger that were interested in and that's how you would process all this data right but. 214 00:31:58.620 --> 00:32:05.370 Edgar Fernando Carrera Jarrin: we're not interested in doing that now what i'd like you to to realize is. 215 00:32:07.380 --> 00:32:09.030 Edgar Fernando Carrera Jarrin: something different. 216 00:32:10.770 --> 00:32:12.450 Edgar Fernando Carrera Jarrin: So let me just go out from here. 217 00:32:14.490 --> 00:32:15.300 Edgar Fernando Carrera Jarrin: Okay, so. 218 00:32:18.480 --> 00:32:22.770 Edgar Fernando Carrera Jarrin: So what i'm gonna do what time is it 830 okay that's fine. 219 00:32:24.630 --> 00:32:31.620 Edgar Fernando Carrera Jarrin: So what i'm going to do is to run this thing as it's you know I just made the change of. 220 00:32:32.940 --> 00:32:45.150 Edgar Fernando Carrera Jarrin: Finding deals just to show you that it works, but then, when I run it as this and i'm going to run it asking it to go through data, so I will put this is true. 221 00:32:45.720 --> 00:32:55.290 Edgar Fernando Carrera Jarrin: Okay, and looked at, we should embrace the change of these files to the data set that we're interested in, because we have this double neo part by default. 222 00:32:56.310 --> 00:33:01.590 Edgar Fernando Carrera Jarrin: But it doesn't really matter for our purposes, for now, so i'm gonna execute this. 223 00:33:03.270 --> 00:33:04.860 Edgar Fernando Carrera Jarrin: Here I have to comply. 224 00:33:06.690 --> 00:33:10.110 Edgar Fernando Carrera Jarrin: always come first, so I execute this granby. 225 00:33:18.420 --> 00:33:19.200 Edgar Fernando Carrera Jarrin: And i'm going to run. 226 00:33:21.750 --> 00:33:22.230 Edgar Fernando Carrera Jarrin: Okay. 227 00:33:23.580 --> 00:33:28.620 Edgar Fernando Carrera Jarrin: And what is going to be run is, at the end of the file. 228 00:33:30.210 --> 00:33:37.620 Edgar Fernando Carrera Jarrin: Right, if you remember, at the end of the file, you can put all the different processes that you want to execute so. 229 00:33:38.550 --> 00:33:49.680 Edgar Fernando Carrera Jarrin: If you do if you do want to have access to this physics analysis toolkit you can execute this line, otherwise you you execute these other line. 230 00:33:50.130 --> 00:34:00.420 Edgar Fernando Carrera Jarrin: And remember here you have all these electrons the Neocons the photons the jets everything that you need if you don't need electrons you can take them out, there is no problem. 231 00:34:00.900 --> 00:34:10.980 Edgar Fernando Carrera Jarrin: But everything that is in this process P, but will be executed and that's what we're going to do as soon as this thing compliance. 232 00:34:13.170 --> 00:34:28.050 Edgar Fernando Carrera Jarrin: And the the outcome of this is going to be the might output root file that you ready, so perhaps and, what is important for us right now is that in wait, it will wait. 233 00:34:28.830 --> 00:34:54.450 Edgar Fernando Carrera Jarrin: Just running over I think the default is 200 events or so something like that, yes, 200 events you remember it just running over 200 events from one of these data data files you get you get a file that waits 5.2 megabytes okay so yeah I I could show you that. 234 00:34:55.500 --> 00:34:58.320 Edgar Fernando Carrera Jarrin: Though it's not really necessary, but let's do it. 235 00:35:00.090 --> 00:35:00.360 Okay. 236 00:35:04.230 --> 00:35:17.370 Edgar Fernando Carrera Jarrin: I would this light I just I just make cms run run in the background right and I dump everything in this log file and I redirect the standard error and output to. 237 00:35:18.180 --> 00:35:30.690 Edgar Fernando Carrera Jarrin: The standard error everything to the output something like this, you can look up this red directors and bash and then I send it to the background, so I can look at the file, while it's running and I can still use my. 238 00:35:32.010 --> 00:35:32.670 Edgar Fernando Carrera Jarrin: My shell. 239 00:35:33.750 --> 00:35:36.210 Edgar Fernando Carrera Jarrin: So let's let's do this thing. 240 00:35:37.830 --> 00:35:42.780 Edgar Fernando Carrera Jarrin: And look how it's developing, of course, of course I. 241 00:36:38.640 --> 00:36:40.530 Edgar Fernando Carrera Jarrin: But I know it, it. 242 00:36:41.610 --> 00:36:49.860 Edgar Fernando Carrera Jarrin: was going to take some time so I just I just put all the results here so let's go through this you're familiar with this anyway right. 243 00:36:51.090 --> 00:36:53.760 Edgar Fernando Carrera Jarrin: So if you run this over data. 244 00:36:54.810 --> 00:37:03.000 Edgar Fernando Carrera Jarrin: Just 200 events with all these processes there okay let's see you know it's about doing something. 245 00:37:04.110 --> 00:37:20.400 Edgar Fernando Carrera Jarrin: You will get an output of 5.2 megabytes yeah you can you can check that with his command and you see that it waits 5.2 megabytes right, and you can do a little calculation, a little estimation, if you go to the data set. 246 00:37:21.660 --> 00:37:28.140 Edgar Fernando Carrera Jarrin: To the official patient data set right, you can see that these data set is. 247 00:37:33.060 --> 00:37:42.450 Edgar Fernando Carrera Jarrin: Which one did I find and now, if you go if you calculate the number of the of this one file remember that this one file. 248 00:37:45.030 --> 00:37:50.700 Edgar Fernando Carrera Jarrin: were in a different data set this one file from double new Park, the first one in this index file. 249 00:37:51.270 --> 00:37:59.940 Edgar Fernando Carrera Jarrin: You you you calculated the number of events in one of the exercises actually have it here linked what you were doing the exercises. 250 00:38:00.900 --> 00:38:19.290 Edgar Fernando Carrera Jarrin: In the cms w three exercises, you were asked to calculate the number of events and you went on to use this edm events, I still from cms this little script and you got the output as 12 a little bit more than 12,000 files. 251 00:38:21.120 --> 00:38:22.200 Edgar Fernando Carrera Jarrin: Okay, so that's. 252 00:38:23.370 --> 00:38:29.100 Edgar Fernando Carrera Jarrin: that's the number of events we haven't this first file and since we process 200 of them. 253 00:38:30.630 --> 00:38:54.060 Edgar Fernando Carrera Jarrin: running over the whole file will result in 300 or around 300 megabytes OK, and then, if we go to the beta said record that exact data set record not the topless expert the double new part, you can see that the this data set has more than 2000 files already. 254 00:38:55.980 --> 00:39:06.450 Edgar Fernando Carrera Jarrin: And right, so you do the little metrics you were figured out that the final size of your. 255 00:39:07.620 --> 00:39:17.340 Edgar Fernando Carrera Jarrin: Execution if you were to execute the whole data set will wait close to one terabyte which is way too large. 256 00:39:20.250 --> 00:39:33.000 Edgar Fernando Carrera Jarrin: I would have trouble even thinking of how to download this thing from wherever it is anyway so it's quite difficult things start to get complicated here. 257 00:39:34.110 --> 00:39:49.740 Edgar Fernando Carrera Jarrin: And so that's what why we skin we reduce the size of the data sets so they are more manageable and we get probably put them in our laptops and so on, so that's what we did let's take another look to this. 258 00:39:52.170 --> 00:39:53.070 let's get stuck. 259 00:39:54.330 --> 00:40:05.430 Edgar Fernando Carrera Jarrin: Nothing worked when you when you do demonstration so that's why it's better for you to to do your hands on anyway so so yeah, believe me, but that is true right. 260 00:40:07.800 --> 00:40:11.370 Edgar Fernando Carrera Jarrin: Okay, so, so we need a way to escape this thing. 261 00:40:12.870 --> 00:40:21.120 Edgar Fernando Carrera Jarrin: to filter this out and just collect information or and reduce the size of these files and and so. 262 00:40:22.170 --> 00:40:34.320 Edgar Fernando Carrera Jarrin: This is best done using what we call ED filters in cms you have talked about, or you have explored the these all these ED analyzers actually. 263 00:40:36.090 --> 00:40:37.260 Edgar Fernando Carrera Jarrin: Just kill this thing. 264 00:40:44.850 --> 00:40:48.000 Edgar Fernando Carrera Jarrin: it's running but it's been too long, so i'm just going to kill it. 265 00:40:53.520 --> 00:40:55.560 Edgar Fernando Carrera Jarrin: yeah So if you. 266 00:40:57.060 --> 00:40:58.050 Edgar Fernando Carrera Jarrin: source. 267 00:41:03.870 --> 00:41:04.620 Edgar Fernando Carrera Jarrin: that's where you. 268 00:41:05.730 --> 00:41:22.530 Edgar Fernando Carrera Jarrin: Are all the code for the analyzers the different analyzers and they all end in analyzer but there's an exception there's one which says simple muto filter which you can imagine, with written, particularly for this workshop. 269 00:41:23.820 --> 00:41:38.760 Edgar Fernando Carrera Jarrin: It does what it says it does right it filters, with it, requiring one new one and one at least one new one good to me on in at least one towel so let's explore how this filter looks like. 270 00:41:42.420 --> 00:41:51.750 Edgar Fernando Carrera Jarrin: In general, you will see that it looks exactly the same as as an analyzer, but it has he did filter here okay. 271 00:41:53.220 --> 00:42:11.670 Edgar Fernando Carrera Jarrin: But otherwise is exactly the same you get the input collections for the different objects, and you can configure it to accept certain requirements, like the minimum PT that you required for the new one, or the mini or the ALA carte remember that we are only seen central nuance. 272 00:42:13.320 --> 00:42:14.520 Edgar Fernando Carrera Jarrin: And the same for the top. 273 00:42:16.350 --> 00:42:33.420 Edgar Fernando Carrera Jarrin: And then, it also has the the filter main section remember the analyzer have the analyze section well filters have the filter section and it returns a boolean so when it is executed through the cms is w path. 274 00:42:33.930 --> 00:42:40.290 Edgar Fernando Carrera Jarrin: It will simply act as a filter it doesn't do anything else, and it blocks the event everything and stops. 275 00:42:42.000 --> 00:42:45.120 Edgar Fernando Carrera Jarrin: processing and then it goes on to the next event. 276 00:42:46.920 --> 00:42:49.680 Edgar Fernando Carrera Jarrin: And so what I have done here is simply. 277 00:42:51.540 --> 00:42:53.040 Edgar Fernando Carrera Jarrin: Look at all the ions. 278 00:42:54.390 --> 00:43:13.740 Edgar Fernando Carrera Jarrin: In impose certain conditions, essentially, that you know it has this Ada angle less than my cut which I get from configuration is a ticket is inputs by configuration, as you can see here loaded in the constructor. 279 00:43:17.190 --> 00:43:30.630 Edgar Fernando Carrera Jarrin: It imposes a cut on the bd of the moon, and also asks for the New York to be tight Okay, and you went through this with Julian you know what type of new and means now. 280 00:43:32.100 --> 00:43:41.400 Edgar Fernando Carrera Jarrin: And we do something similar for the Tower is a little bit more complicated remember yesterday Julia was talking about all these little helpers. 281 00:43:42.930 --> 00:43:53.550 Edgar Fernando Carrera Jarrin: Political photo discriminated and you apply similar restrictions cinematical and also with this flat this this is essentially boolean. 282 00:43:54.690 --> 00:44:08.010 Edgar Fernando Carrera Jarrin: The decay mode, you ask for this us for the Tower to be tightly isolated, you went tight rejection of electrons and tight rejection of me odds. 283 00:44:08.520 --> 00:44:23.880 Edgar Fernando Carrera Jarrin: And you don't care which one it is just look over the collection of towels look over the collection of neurons and find one if you find find one of those, then the event passes, otherwise it just gets blocked. 284 00:44:26.760 --> 00:44:29.340 Edgar Fernando Carrera Jarrin: Okay, you can configure this, as I said. 285 00:44:31.230 --> 00:44:34.470 Edgar Fernando Carrera Jarrin: With the poet configuration file. 286 00:44:38.130 --> 00:44:38.910 Edgar Fernando Carrera Jarrin: Which is here. 287 00:44:40.830 --> 00:44:41.400 Edgar Fernando Carrera Jarrin: and 288 00:44:44.130 --> 00:44:47.490 Edgar Fernando Carrera Jarrin: And you should have commented out yeah. 289 00:44:49.110 --> 00:44:57.870 Edgar Fernando Carrera Jarrin: up like were actually there are two filters, the first one here this filter refers to a filter which was already. 290 00:44:58.320 --> 00:45:16.350 Edgar Fernando Carrera Jarrin: written in C in cms is w that allows you to filter by by trigger we're not going to do that because i'd like to show you or i'd like you to see later in the hands on lesson, how is it to to deal with the trigger to get the name and maybe the acceptance, be it. 291 00:45:18.000 --> 00:45:30.480 Edgar Fernando Carrera Jarrin: Because it's not necessarily trivial so we're going to keep the trigger me we're not going to ask anything about the trigger so let's just keep it there, but I have replaced this trigger in case you want to filter like that. 292 00:45:32.010 --> 00:45:43.440 Edgar Fernando Carrera Jarrin: The drawback of these analyzer of this filter is that it's just it's it just looks at the acceptance of the trigger whether the event was accepted or not. 293 00:45:43.980 --> 00:45:59.190 Edgar Fernando Carrera Jarrin: And it doesn't know anything about freescale so that could be a little dangerous you always have to check whether the priests, that the trigger was Bruce freescale or not and that's a whole study by itself when you use this data. 294 00:46:00.360 --> 00:46:06.930 Edgar Fernando Carrera Jarrin: Okay, but we can use our simple filter so one thing that we can do is just to uncommon this. 295 00:46:08.160 --> 00:46:17.880 Edgar Fernando Carrera Jarrin: and give it the parameters right so i'm asking i'm reinforcing essentially or the analysis, the original simplified analysis basically applies this cuts. 296 00:46:18.390 --> 00:46:31.890 Edgar Fernando Carrera Jarrin: And sort of reinforces the cards, as in the in the trigger Okay, and gives us minimum values for the pts and there's a regions of India. 297 00:46:32.310 --> 00:46:48.030 Edgar Fernando Carrera Jarrin: So we're going to stick to that and we're going to apply the same changes so we could say this, and once you run it, you have to believe me, because i'm not going to do it anymore, once you run it, you will get a file. 298 00:46:51.750 --> 00:46:52.320 Edgar Fernando Carrera Jarrin: You know. 299 00:46:54.150 --> 00:46:57.030 Edgar Fernando Carrera Jarrin: Oh, one thing that I forgot, very important. 300 00:46:58.350 --> 00:47:18.030 Edgar Fernando Carrera Jarrin: Once you uncommitted this filter right you get a new muto filter right here is your neutral filter configured in this way, which configured based code right, this is our filter the c++ implementation is called this way. 301 00:47:19.620 --> 00:47:29.220 Edgar Fernando Carrera Jarrin: And once you do that, you can add this process to the path so I can go here and foods process. 302 00:47:30.810 --> 00:47:32.490 Edgar Fernando Carrera Jarrin: That new. 303 00:47:33.570 --> 00:47:35.640 Edgar Fernando Carrera Jarrin: filter of whatever the name was. 304 00:47:37.080 --> 00:47:53.970 Edgar Fernando Carrera Jarrin: and put it somewhere in this bath OK, so the code will go through all these different analyzers but also through the the filter and if the filter finds that the event is not good, then. 305 00:47:55.380 --> 00:47:56.610 Edgar Fernando Carrera Jarrin: Then it will just. 306 00:47:57.690 --> 00:48:02.100 Edgar Fernando Carrera Jarrin: Stop the processing and jump to the other, to the other event. 307 00:48:04.290 --> 00:48:07.350 Edgar Fernando Carrera Jarrin: Okay, so someone exit this. 308 00:48:08.520 --> 00:48:09.600 Edgar Fernando Carrera Jarrin: that's the way you do it. 309 00:48:10.800 --> 00:48:19.500 Edgar Fernando Carrera Jarrin: And if you do that, and if you run, you will end up with a file of just 22 kilobytes Okay, maybe into hundred events. 310 00:48:20.340 --> 00:48:29.940 Edgar Fernando Carrera Jarrin: It turns out that it lived all the 200 events, and this is, I know that, because the two the two kilobytes to 54 sides for an empty file. 311 00:48:30.270 --> 00:48:46.860 Edgar Fernando Carrera Jarrin: But in any way that works that that really works if you if you run over more events you get a file size, which is around point 4% less I mean you'll reduce the data set 2.4%. 312 00:48:48.120 --> 00:48:55.500 Edgar Fernando Carrera Jarrin: If you do the math again, you will see that the whole data set can be reduced to around three gigabytes. 313 00:48:57.240 --> 00:49:09.780 Edgar Fernando Carrera Jarrin: Alright, this is, this is a big step it goes with file sizes of the order of gigabytes you can actually download them to your computer and start processing them and look at them more carefully. 314 00:49:10.770 --> 00:49:17.310 Edgar Fernando Carrera Jarrin: And of course we cannot do this it will take us a long time in our single machine. 315 00:49:18.180 --> 00:49:29.610 Edgar Fernando Carrera Jarrin: But fortunately we have access to the computing infrastructure at CERN and I use this hd calendar that they have on Alex plus machines at CERN. 316 00:49:30.000 --> 00:49:44.670 Edgar Fernando Carrera Jarrin: And I process all these for you in a very similar way actually I took out many of the things here like electrons protons even jets I didn't put in there, because I want them I want I wanted the files to be. 317 00:49:45.600 --> 00:50:02.310 Edgar Fernando Carrera Jarrin: Small and okay I process them, and those are the files, the output of all this, processing, for all the data sets that we need those are the files that I was asking you to copy Okay, and you will find them. 318 00:50:03.960 --> 00:50:16.140 Edgar Fernando Carrera Jarrin: Here at this place, which is my my son my son box and if you have if you haven't done that so so here they are right, look at the sizes, they are of the order of megabytes. 319 00:50:16.560 --> 00:50:27.630 Edgar Fernando Carrera Jarrin: Okay, in total, they are 1.5 gigabytes so you have process, like several terabytes of data, maybe 10s of terabytes of data. 320 00:50:28.230 --> 00:50:37.800 Edgar Fernando Carrera Jarrin: And you have managed to have we have managed to reduce the size to 1.5 gigabytes and performer to in order to perform our analysis. 321 00:50:38.340 --> 00:50:53.430 Edgar Fernando Carrera Jarrin: So you have everything here, you can download it as a SIP file or a tar file, I suppose, and put it somewhere available in your container I usually if you look at my instructions here. 322 00:50:54.510 --> 00:51:00.840 Edgar Fernando Carrera Jarrin: The first ones from before I usually fire up my container. 323 00:51:02.970 --> 00:51:05.640 This one is not the one that i'm looking for. 324 00:51:08.490 --> 00:51:11.280 Edgar Fernando Carrera Jarrin: yeah I usually fire up my container. 325 00:51:13.620 --> 00:51:14.370 What is that thing. 326 00:51:17.250 --> 00:51:35.340 Edgar Fernando Carrera Jarrin: yeah I usually fire up my container a mountain some volume of my computer into an area of my darker so usually copy things from outside to this area, so I can see them in the container. 327 00:51:36.870 --> 00:51:39.450 Edgar Fernando Carrera Jarrin: That way advice I do Ls. 328 00:51:40.650 --> 00:51:43.650 Edgar Fernando Carrera Jarrin: playground, and I put him somewhere in. 329 00:51:51.840 --> 00:52:02.760 Edgar Fernando Carrera Jarrin: When I was preparing this I made sure I had these files copied over, and so I have them already to the root files, I have them there in that. 330 00:52:03.180 --> 00:52:13.320 Edgar Fernando Carrera Jarrin: In that volume that I mounted so I can access them, really, really quickly and, as I said, we're going to use these these these are going to be our input for the next. 331 00:52:13.770 --> 00:52:23.160 Edgar Fernando Carrera Jarrin: session, which is a hands on session, and you will have to work with that, so we are we have completed by now the step number one. 332 00:52:23.610 --> 00:52:41.520 Edgar Fernando Carrera Jarrin: So all this thing all the process processing, which takes a lot of computing resources we're done with this and it does take a lot of resources and that's why you're going to learn starting starting from today how to access or run these kind of things on the cloud. 333 00:52:43.800 --> 00:52:50.070 Edgar Fernando Carrera Jarrin: And this route files are the files that which is obtained so for the hands on session what you would. 334 00:52:50.370 --> 00:53:03.000 Edgar Fernando Carrera Jarrin: What you will be doing is to go through this event loop analysis and learn all about this processes and updating the the Nice blots or make a replica of the simplified analysis that was already done by Stephen. 335 00:53:04.050 --> 00:53:05.220 Edgar Fernando Carrera Jarrin: lunch okay. 336 00:53:07.410 --> 00:53:09.840 Edgar Fernando Carrera Jarrin: I hope this wasn't an overkill. 337 00:53:12.720 --> 00:53:16.500 Edgar Fernando Carrera Jarrin: If there are questions i'll be happy to take them. 338 00:53:19.020 --> 00:53:21.090 Edgar Fernando Carrera Jarrin: Otherwise, we can go for for coffee. 339 00:53:47.430 --> 00:53:47.880 Edgar Fernando Carrera Jarrin: Okay. 340 00:53:51.750 --> 00:53:53.670 Edgar Fernando Carrera Jarrin: So, shall we shall we stop here. 341 00:53:55.920 --> 00:53:57.270 Matthew Bellis: i'll go ahead and stop the recording.
