Instructions to run nTuplizers

Offline (BTagAnalyzer)

The Offline ntuplizer can be run and configured through RecoBTag/PerformanceMeasurements/test/runBTagAnalyzer_cfg.py, to run it with the latest defaults

cmsRun runBTagAnalyzer_cfg.py defaults=Run3 runOnData=(True or False, depending on your needs) maxEvents=10

Online (HLTBTagAnalyzer)

The Offline ntuplizer can be run and configured through RecoBTag/PerformanceMeasurements/test/runBTagAnalyzer_cfg.py, to run it with the latest defaults

cmsRun runHLTBTagAnalyzer_cfg.py defaults=Run3 runOnData=(True or False, depending on your needs) maxEvents=10

General information

The content of the output nTuple is by default empty and has to be configured according to your needs. The store*Variables options have been removed. The new variable configuration can be customized in the file RecoBTag/PerformanceMeasurements/python/varGroups_cfi.py. New variables need also to be added (apart from adding them in the code) in RecoBTag/PerformanceMeasurements/python/variables_cfi.py

How to get the latest HLT configuration (GRun / on lxplus only)

Recent versions are also stored already in here For MC:

hltGetConfiguration /dev/CMSSW_12_2_0/GRun \
--full \
--offline \
--unprescale \
--mc \
--process HLT2 \
--globaltag auto:phase1_2021_realistic \
--max-events 10 \
> tmp.py

edmConfigDump tmp.py > HLT_dev_CMSSW_12_2_0_GRun_configDump_MC.py

For data:

hltGetConfiguration /dev/CMSSW_12_2_0/GRun \
--full \
--offline \
--unprescale \
