The aim of the workshop is:

  • get familiar with CMT (Configuration Management Tool). This is the environment used to run ATHENA and maintain/develop its packages.
  • introduce a beginner to ATHENA and its concepts such as Algorithms, Tools, DataStorage and the like
  • explain the usage of python scripts (jobOptions) in order to steer ATHENA
  • Excersise on a part of the ATHENA-chain: do reconstruction and analysis
