This framework has 3 modules that have to be run in this order :
1- DijetRootTreeMaker which produce the Ntuples : https://github.com/lattaud/DijetRootTreeMaker.git
2- DijetRootTreeAnalyzer which reduce the Ntuple by applying the selection and allow to run JEC on the fly : https://github.com/lattaud/DijetRootTreeAnalyzer.git
3- NewGammaJet which is the plotting step : https://github.com/lattaud/NewGammaJet.git
Instruction can be found in each step repository.
This module is the first step of the gamma + jet analysis :
to run on 2016 data stay on the master branch to run on 2017 data switch to 9_2_X branch
pick up your branch and then check instruction here: https://github.com/lattaud/DijetRootTreeMaker/blob/master/instructions/GammaJetTree_Instruction.txt
