SFT/Key4hep Meeting
===

Attendees: Benedikt, Andre, Swathi, Yurii, Jenny, Juan, Leonhard, Carsten,

Apologies:

Date: June 20, 2023

## Round The Table

#### Benedikt

* Frame: Waiting for feedback on the metadata, 
   * Implement the metadata conversion in the converters

#### Swathi

* All major overlaps removed from the CLD_LAr detector
   * [ ] PR: 
   * Shared steering file with Brieuc

#### Yurii

* Trying to write files with the python interfaces, but no output files are generated. Under investigation.
* Then move to implement some Gaudi Algorithm

#### Jenny

* New LCIO to EDM4hep converter presentation
   * See slides attached from Finn Johannsen (?)

* ECFA Reconstruction Workshop July 11--12 is open
   * https://indico.cern.ch/event/1283129/
* ECFA Paestum Workshop, October 11--13, is also open
   * https://agenda.infn.it/event/34841/
   * Abstract deadline: July 15
   * Includes a Key4hep tutorial on October 10

#### Juan

* CEPC Workshop in Edinburgh, July 3--6

* New test for podio/EDM4hep backward compatibility (see slides)
   * subdetectorHitNumbers renaming (capitalisation) breaks.
       * The member no longer has any content

* Working on Presentation for EP RnD Software meeting

#### Leonhard

- Generation of tracking performance plots for the CLD detector
   - For `LCIO` input the relations look correct both with old and new conversion
   - New conversion still broken on `edm4hep` input
       - E.g., relation to MCParticles when convertiong back from LCIO cannot be resolved, because original EDM4hep::MCParticle is not known
   - Will try to just get them done now with `LCIO` input
- $WW/e\nu W$ benchmark analysis
   - No progress, still need to fix $\varphi^*$
   - Try out on reconstructed data after performance plots above
- ACTS tracking
   - Tried (to try) out `k4ActsTracking` but did not make it far, looks like there is a naming conflict (`GeoService`)
   - There is also much more unmerged stuff in the development fork
- Summer Student
   - "Including time information in track reconstruction for future colliders"
   - Starts next Monday
   - I guess we should discuss the topic a bit more soon?
- FCC Software Meeting talk 26.06. (also next Monday)
   - "Status of CLD tracking"
   - "Guidance on what to use, known issues/tricks, what results you can get in term of reconstructed tracks"

#### Carsten

* Converted LCIO files to EDM4hep
* Implementing first Gaudi Algorithm based on k4-project-template
* Segmentation fault


## TODO

* CLD Reco
   * [ ] CLDConfig Repository
   * [ ] Save history from ClicPerformance of FCCConfig

- [ ] sign up for iLCDirac: https://ilcdirac-doc.web.cern.ch/
   - [x] Leonhard
   - [x] Juan
   - [ ] Swathi
   - [x] Carsten
   - [ ] Jenny

- [ ] Need k4FWCore with Frame Reader

- [ ] add k4Geo environment variable to eventually replace LCGEO env var
