1. Producinh the comparispon plots of sig/bkg photons
>mkdir SigBkgComparisonsPlots
>root -l -b -q DrawComparisonPlots.C
--> output plots under SigBkgComparisonsPlots/

2. training for EB and EE separately

 root -l -b -q TMVAClassification_EB.C
 root -l -b -q TMVAClassification_EE.C

--> weight files:  PhotonID_Weight/weights/*.xml
--> output root files:  PhoID_barrel_Train_GJetMC.root  and  PhoID_endcap_Train_GJetMC.root
    
 >root -l
 >TMVA::TMVAGui("PhoID_barrel_Train_GJetMC.root")
 --> comparisons of inputs, correlation matrix, output, eff., ....

3. application in the analysis:
root -l -b -q evaluateMVA_AnySample.C
--> Output_mvares_included.root
    Cut on "idmva_res" to suppress bkg

4. To get the comparison plots of photon ID MVA between signal photon and fake photon, in EB and EE separately
root -l -b -q DrawComparisonPlots.C   #together with plotting style hggPaperStyle.C

--> *.png / *.pdf plots

rm -rf SigBkgComparisonsPlots/ PhotonID_Weight/ *.png *.pdf *.root
