Description

Validation package for b-tagging : contain useful scripts for validation purpose. Use the DQMOffline/RecoB package.

Public interface

BTagPerformanceAnalyzerMC : analyzer optimized to run on MC and produce all intersting variables to check the reliability of the b-tagging algorithms. Produce also performance plots.

BTagValidator
bTagValidation : define in bTagAnalysis_cfi.py. Basic module to use BTagPerformanceAnalyzerMC.
bTagValidationFirstStepData : define in bTagAnalysis_firststep_cfi.py. Clone of bTagAnalysis (DQMOffline/RecoB/python/bTagAnalysisData_cfi.py). To run the first step on Grid for Data.
bTagValidationFirstStep : define in bTagAnalysis_firststep_cfi.py. Clone of bTagValidation. To run the first step on Grid for MC.
bTagValidationHarvestData : define in bTagAnalysis_harvesting_cfi.py. Clone of bTagAnalysis (DQMOffline/RecoB/python/bTagAnalysisData_cfi.py). To harvest the histograms for Data.
bTagValidationHarvest : define in bTagAnalysis_harvesting_cfi.py. Clone of bTagValidation. To harvest the histograms for MC.

file validation_cfg.py : to be run as ' cmsRun validation_cfg.py jets="ak5PF" '. Other jets label possible : "ak5PFJEC", "ak5PFnoPU". Other options which could be changed : runOnMC(True for MC ; False for DATA) ; useTrigger(False:no trigger filter used ; True:trigger filter used, path could be modified in the cfg, default:HLT_PFJet40) ; tag(put here your global tag).
directory GridValidation/ : tools to run on Grid, cfg based on validation_cfg.py. In README, the step to run on the Grid are listed.

Scripts for validation automation perhaps to be updated if the modifications in the Validation/RecoB and DQMOffline/RecoB are released
