MicroAOD to diPhotonTrees

This package depends on flashgg.

(Follow what is done here from P. Musella: https://github.com/cms-analysis/flashgg/tree/master/MetaData and here from C. Rovelli: https://github.com/musella/diphotons/tree/master/fullAnalysisRoma )

Step 1) Produce catalogue of MicroAODs

Once MicroAOD files are produced run these scripts to create the json file (catalogue) and compute the weights:

• fggManageSamples.py -C testMonoH -V import
• fggManageSamples.py -C testMonoH review
• fggManageSamples.py -C testMonoH check

Step 2) Copy json to the scripts/list* directory

• Copy directly from FLASHgg catalogue or list as produced in Step 1.
• If json file is not separated by name can extract smaller json files with: ./runExtractJSONS.sh which calls: python extractJSONS.py -i input.json -o samplename -d outputdir

Step 3) Extract files and weights

This creates .list and .weight files in list* directory

Write the proper name of the catalogue in the extract*.py scripts and write the name of the samples in:

• python extractWeights.py
• python extractFiles.py

OR run ./runExtractFilesAndWeights.sh does the same thing (takes input list of .json files and outputs weight and files in same list dir.)

Step 4) Run in local the diphoton analyzer (from python directory):

• Write by hand one microAOD file that can be taken from the json file
• Fix by hand xsec and sumDataSet that can be found from the json file corresponding
• Optional: put in PU reweighting file
• called by cmsRun diPhoAna.py

Step 5) Run in batch the diphoton analyzer (from script directory):

To make it works one needs:

• a list of files in script/list directory with the name of the samples
• a list of weights in script/list directoy with the name of the samples
• the name of the list directory needs to be written in submitBatchDiPho.py
• the value of the xsec
• add optional PU reweighting & input PU reweighting file
• the output directory either in eos or in lxpus (this has to be fixed in the submitBatchDiPho.py script by hand)

Example on how to run:

./submitBatchDiPho.py --cfg diPhoAnaBATCH.py GJets_HT-100to200 0 7 pippo 1534. 1 

NB. The name GJets_HT-100to200 has to match the one of the .list and the .weight files.

Can also run: ./submitAll_DiPhioton.py

Step 6) Manage the output trees before making plots

From the macro directory:

• Merge the output files with ./mergeTrees.sh
• Add the weights to the trees with addWeightsToTree.cc run by ./weighTrees.sh which addWeights for lumi (in pb^-1)
• Merge the species with ./mergeSpecies.sh

NB. The structure of how to use these scripts can be seen in doAll.sh

Step 7) Produce plots

The analysis is done in CMSSW_7_4_15

• make (to compile)
• ./main (to run)

In main.cpp set the following bools:

• (makePURWfiles) : calls ReweightPU.cpp --- makes PURW files for samples)
• (doReweightPU) : opens PURW files --- does PURW instead of weighting=1
• (doBlind) : blinds data in Plots --- blinds the data mass & met distributions
• (doPlots) : calls Plotter.cpp --- makes the histos for each sample individually
• (doComb) : calls Combiner.cpp --- overlays and stacks samples in plots
• (doABCD) : calls ABCDMethod.cpp --- does the ABCD/C&C analysis

The style for the plots is set with Style.cpp.
