Running ttbar package

Setting up my ttbar analysis package

The analysis package only contains

• a clone of UserAnalysis/AnalysisSkeleton
• a clone of AnalysisExamples/ttbar
• the simpleTTbar class that dumps a (nearly) complete ntuple with all AOD information needed for a ttbar analysis on full simulation Monte Carlo

1. Go to the directory where you want to install the package. The package will appear in a subdirectory named TTBarAnalysis of the chosen directory. If you have run the previous examples then PhysicsAnalaysis/AnalysisCommon may be good place, but you can also just put it in /project/atlas/users/<userid>/ttbar.
2. Check out the TTBarAnalysis package from the NIKHEF/ATLAS CVS repository: cvs -d/project/atlas/cvs co -r v00-00-02 TTBarAnalysis
3. Go to the cmt directory: cd TTBarAnalysis/cmt
4. Execute cmt config
5. Execute source setup.csh
6. Build the library: gmake
7. Go to the run directory: cd ../run
8. Execute get_files PDGTABLE.MeV. This file needs to be present in your run directory for Athena to work.
9. Link to the ttbar input directory: ln -s /project/atlas/users/verkerke/RomeData/recov10/4100 AOD
10. Create the pool file catalog: pool_insertFileToCatalog AOD/*/*AOD.pool.root

Running my ttbar analysis package

1. If not already done, goto the cmt directory and execute source setup.csh
2. Go to the run directory: cd /.../TTBarAnalysis/run
3. Execute: athena.py simpleTTbar_jobOptions.py
