NanoAOD Skim

nanoAOD skiming code for H->ZZ->2l2Q studies.

Code setup

1. Step: 1: Get CMSSW release

   cmsrel CMSSW_10_6_30
   cd CMSSW_10_6_30/src
   cmsenv

2. Step: 2: Get official nanoAODTools

   git clone [email protected]:cms-nanoAOD/nanoAOD-tools.git PhysicsTools/NanoAODTools
   cd PhysicsTools/NanoAODTools
   git checkout 65359982275c476834ad4b37363d658166881f12 # Updated to commit on 16 June 2023 in official nanoAOD-tools

3. Step: 3: Get our analysis repository

   cd $CMSSW_BASE/src
   git clone [email protected]:YujiLee301/nanoAOD_skim.git PhysicsTools/NanoAODTools/python/postprocessing/analysis/nanoAOD_skim
   cd PhysicsTools/NanoAODTools/python/postprocessing/analysis/nanoAOD_skim
   git submodule init
   git submodule update
   cd -
   cmsenv
   # patch PhysicsTools/NanoAODTools/python/postprocessing/analysis/nanoAOD_skim/nanoAOD_tools.patch
   cp PhysicsTools/NanoAODTools/python/postprocessing/analysis/nanoAOD_skim/data/btag/*.csv PhysicsTools/NanoAODTools/data/btagSF/.
   scram b
   voms-proxy-init --voms cms --valid 168:00

   (Optional: Fix git repo)

   find PhysicsTools/NanoAODTools/python/postprocessing/analysis/nanoAOD_skim/.git/ -name "*.py*" -delete

4. Step: 4: interactive running

   cd $CMSSW_BASE/src/PhysicsTools/NanoAODTools/python/postprocessing/analysis/nanoAOD_skim
   git clone -b v2.3.5 https://github.com/JHUGen/JHUGenMELA
   sh JHUGenMELA/MELA/setup.sh -j 8
   cd JHUGenMELA/MELA
   make
   cd $CMSSW_BASE/src/PhysicsTools/NanoAODTools/python/postprocessing/analysis/nanoAOD_skim
   python post_proc.py

5. batch job submission.

   1. Crab-job submission

      cd crab/
      voms-proxy-init -voms cms --valid 200:00
      source /cvmfs/cms.cern.ch/crab3/crab.sh
      crab submit -c crab_cfg.py

   2. Step: 5 (b): Condor-job submission

      1. In the file condor_setup.py, specify the correct input text file from which you need to take input NanoAOD DAS names. Also, updated the output EOS path. Then do the following:

         cd $CMSSW_BASE/src/PhysicsTools/NanoAODTools/python/postprocessing/analysis/nanoAOD_vvVBS
         # Edit condor_setup.py, then
         python condor_setup.py
         # Set proxy before submitting the condor jobs.
         voms-proxy-init -voms cms --valid 200:00
         condor_submit <Files-created-from-above-command>.jdl
