Setup CMSSW First

CMSSW_13_0_10 is recommended CMSSW for RUN3 NANOAODv12

source /cvmfs/cms.cern.ch/cmsset_default.sh
cmsrel CMSSW_13_0_10
cd CMSSW_13_0_10/src
cmsenv
git clone https://github.com/jshin96/SNUSKNANO.git
scram b -j 8

NANOAOD Production

Recommendation available: https://gitlab.cern.ch/cms-nanoAOD/nanoaod-doc/-/wikis/Releases/NanoAODv12

make sure you use the correct ${GT} and ${ERA} defined in corresponding NanoAOD version

Private MC NANOAOD Production

cmsDriver.py NANO -s NANO --mc --conditions ${GT} --era ${ERA} --eventcontent NANOAODSIM --datatier NANOAODSIM --customise_commands="process.add_(cms.Service('InitRootHandlers', EnableIMT = cms.untracked.bool(False)));process.MessageLogger.cerr.FwkReport.reportEvery=1000" -n -1 --no_exec

Private DATA NANOAOD Production

cmsDriver.py NANO -s NANO --data --conditions ${GT} --era ${ERA} --eventcontent NANOAOD --datatier NANOAOD --customise_commands="process.add_(cms.Service('InitRootHandlers', EnableIMT = cms.untracked.bool(False)));process.MessageLogger.cerr.FwkReport.reportEvery=1000" -n -1 --no_exec

Adding Variables

Inside Producer/python directory, there are python files for different objects that can be used to add variables that you need. You can define pretty much any variables using any objects defined in DataFormats. This should cover more than enough. I am still figuring out on how to implement purely calculated variables that user wants to use.

Once you have modified the python file to add variables that you want, you need to add that to --customise_commands so it is implemented in cmsRun code

cmsDriver.py NANO -s NANO --mc --conditions ${GT} --era ${ERA} --eventcontent NANOAODSIM --datatier NANOAODSIM --customise_commands="process.add_(cms.Service('InitRootHandlers', EnableIMT = cms.untracked.bool(False)));process.MessageLogger.cerr.FwkReport.reportEvery=1000\n from SNUSKNANO.Producer.##your_python_file##.py import *; process = Prep##Object##CustomNanoAOD(process)" -n -1 --no_exec

Crab Run

For Crab Submission, there is a template crab file in crab directory. IMPORTANT: If you run on CRAB, it is important to add fakeNameForCrab = cms.untracked.bool(True) to the configuration of the NanoAODOutputModule in the CMSSW cfg file (and to run a single instance of it - this should normally be the case).
