ProductionFromNano

Tools for running HEPHY ntuple production, based on WAW ntuple production, from NanoAOD.

Port of tools by A. Kalinowski, M. Bluj et al. based on KLUB/LLR trees to CMS NanoAOD

---

• NanoEventsSkeleton.{h,C}: interface to NanoAOD ntuples produced from NanoAOD with MakeClass tool, it needs be updated after each modification of NanoAOD format.
• HTauTauTreeFromNanoBase.{h,C}: base class to translate to WAW format
• HElTauhTreeFromNano.{h,C}: specialization for the e+tau channel
• HMuTauhTreeFromNano.{h,C}: specialization for the mu+tau channel
• HTauhTauhTreeFromNano.{h,C}: specialization for the di-tau channel
• HTTEvent.{h,cxx}: definition of WAW analysis classes
• PropertyEnum.h, TriggerEnum.h, FilterEnum.h: definition of enums, (re)generated by the tool
• AnalysisEnums.h, SelectionBitsEnum.h: definition of enums
• convertNano.py: script to run conversion - currently not functional, use run.py and convertNanoParallel.py (but contains important lines to run on data)
• run.py: script to run NanoAOD-to-SyncNtuple conversion in parallel, calls convertNanoParallel.py
• convertNanoParallel.py: script to run conversion
• Missing: production tools, need be taken modified from old WAW repo

How to run

• Get proxy with voms-proxy-init -voms cms.
• Source CMSSW

  cd $CMSSW_BASE/WawTools/NanoAODTools
  cmsenv
  

• Get filelists specified in sample_collection.json to be used for production. Only needed to run once or when samples are updated.

  python getFilelists.py
  

• Jobs can be submitted locally (local) on a batch system (batch) or on HTCondor (condor) with option -t WHERE. When submitting locally option -j N specifies the number of parallel jobs (default=8).
• Channel can be specified with option -c {et, mt, tt, all}. Make sure when running over data to give the correct channel.
• Sample can be specified with option -s SAMPLE.
  • Single sample: give the relative path to the .txt file (NOTE: you can use tab-complete). E.g

  -s samples/mc/signal/VBFHToTauTau_M125_13TeV_powheg_pythia8_RunIIFall17NanoAOD_12Apr2018.txt
  

  • To submit multiple samples several keywords are hardcoded: mc, data, dy, diboson, ewk, signal, st, tt, w

  -s signal
  

• Further information on run option with option -help
• When jobs are running on batch you can check the status with.

  python bookkeeping.py
  

• To merge samples run

  python mergeSamples.py
  

  Only samples that are already finished are merged.
