  1. Athena for combined TB? Why would one consider it? Pros and cons

  2. Possible Advantages • Learn some new tools like C++, Athena, databases… • Reconstruction code “reusuable” later for “real” data taking; bigger community can profit • Fortran is about to “die”. Thus, motivation to develop code in Fortran low • Use of code which already exists or could be easily modified • Profit from code development to do TB analysis for EM modules or from ROD package • “current” reconstruction code benefits from using/adapting it in more realistic environment

  3. Negative Aspects • Development more time-consuming • Most of us have to learn first C++, Athena… • Still lots of changes in Athena framework, you have to keep track of • Fortran code for HEC analysis ready, so not much need to change this part for combined test • Work in new framework difficult due to missing documentation, changes in Gaudi/Athena, developing event data model • Accept working in ATLAS environment • keep code in “running” status • Obey coding standards • interaction with larger community

  4. Decision • Decision on which framework to use depends crucially on • Time-scale of project • Manpower • Interest of people actually writing the code • Interest of people doing the analysis later on (to a lesser extend) • In the beginning it’s hard to get used to all this new stuff & framework unstable • either you work full-time or in an unefficient way

  5. Comments/Suggestions Once TB converter available • Try using already existing code e.g. LArHit • Produce cells using CaloCell, LArCell • Try keeping the reconstruction flow and put in your own code for corrections • Speak to reconstruction people if current code is not “flexible” enough • If you write “new” code try to keep similar naming conventions for algorithms, variables as available in LAr code  makes life easier for newcomers • Probably quite some algorithms/methods can be easily translated from Fortran to C/C++, but no use doing “ftoc” because of framework dependencies. If you prefer Fortran no use switching to Athena
