Description
The GSI online-offline analysis system Go4 is a ROOT based framework for medium
energy ion- and nuclear physics experiments. Its main features are a multithreaded
online mode with a non-blocking Qt GUI, and abstract user interface classes to set
up the analysis process itself which is organised as a list of subsequent analysis
steps. Each step has its own event objects and a processor instance. It can handle
its event i/o independently. It can be set up by macros or by generic a GUI. With
respect to the more complex experiments planned at GSI, a configurable network of
steps is required. Multiple IO channels per step and multiple references to steps
can be set up by macros or via generic GUI. The required mechanisms are provided by
an upgrade of the Go4 analysis step manager using the new ROOT TTasks. Support for
IO configuration and references across the task tree is provided.
