Producing microAODs

The so-called microAOD format is a subset of the MINIAOD produced by the flashgg framework, adding specific photon-related informations.

Only high level objects such as photons, leptons, jets and MET are stpored in microAD by default. If additional informations are needed, they need to be added explicitely to the output.

The package flashgg/MetaData contains the scripts related to microAOD production. To start with, go to flashgg/MetaData/work.

cmsenv
cd ${CMSSW_BASE}/src/flashgg/MetaData/work

The folder contains the script prepareCrabJobs.py, which sets up the crab3 tasks needed to generate microAODs.

First, you need to set up the crab3 and grid environment.

source /cvmfs/cms.cern.ch/crab3/crab.sh
voms-proxy-init --voms cms --valid 168:00

Then, prepare a json file with the list of datasets to be processed, as in the example below.

{
    "data" : ["/DoubleElectron/CMSSW_7_0_6_patch1-GR_70_V2_AN1_RelVal_zEl2012D-v1/MINIAOD"
              ],
    "sig"  : ["/GluGluToHToGG_M-125_13TeV-powheg-pythia6/Spring14miniaod-PU20bx25_POSTLS170_V5-v2/MINIAODSIM",
              "/VBF_HToGG_M-125_13TeV-powheg-pythia6/Spring14miniaod-PU20bx25_POSTLS170_V5-v1/MINIAODSIM",
              "/WH_ZH_HToGG_M-125_13TeV_pythia6/Spring14miniaod-PU20bx25_POSTLS170_V5-v2/MINIAODSIM",
              "/TTbarH_HToGG_M-125_13TeV_pythia6/Spring14miniaod-PU20bx25_POSTLS170_V5-v1/MINIAODSIM",
              "/TTbarH_HToGG_M-125_13TeV_amcatnlo-pythia8-tauola/Spring14miniaod-PU20bx25_POSTLS170_V5-v1/MINIAODSIM",
              "/GluGluToHHTo2B2G_M-125_13TeV-madgraph-pythia6/Spring14miniaod-PU20bx25_POSTLS170_V5-v1/MINIAODSIM"
              ],
    "bkg"  : ["/GJet_Pt20to40_doubleEMEnriched_TuneZ2star_13TeV-pythia6/Spring14miniaod-PU20bx25_POSTLS170_V5-v1/MINIAODSIM",
              "/GJet_Pt40_doubleEMEnriched_TuneZ2star_13TeV-pythia6/Spring14miniaod-PU20bx25_POSTLS170_V5-v2/MINIAODSIM",
              "/DYJetsToLL_M-50_13TeV-madgraph-pythia8-tauola_v2/Spring14miniaod-PU20bx25_POSTLS170_V5-v1/MINIAODSIM"
              ]
}

To generate the crab3 configuration run (see ./prepareCrabJobs.py --help for the full list of options).

./prepareCrabJobs.py -p <parameterSet> \
		     -C <microAODCampaginName> \
		     -s <jsonFileWithDatasetList> \
		     --mkPilot

This will create a folder containing all the crab3 configuration files, the CMSSW parameterSet as well as a file called config.json containing the dump of all the script options. The latter can be used to reproduce the same configuration (using the --load option), eg when adding more dataset to the same campaign.

./prepareCrabJobs.py --load <previous_config.json> \
		     -s <jsonFileWithAdditionalDatasets>

The --mkPilot option will create an additional crab3 configuration that can be used to run on a single file, before submitting the whole list of tasks.

You can now lanch the microAOD production.

cd <microAODCampaginName>
echo crabConfig_*.py | xargs -n 1 crab sub
## or using GNU parallel 
## parallel 'crab sub {}' ::: crabConfig_*.py

Running on microAODs

Set up file catalog

See instructions in flashgg/MetaData/README.md

File catalog for ExoPhys14ANv1 is already in git (ie you can skip this part). To see the list of datasets run:

fggManageSamples.py -m diphotons -C ExoPhys14ANv1 list

Jobs configuration

Full-framework and FWLite configurations are stored in Analysis/config. Example of how to run them:

cd Analysis/config
cp -p jobs_gamjets_gamgam.json myjobs.json
emacs -nw photonIdAnalyzer.py myjobs.json

# test with 100 events
fggRunJobs.py --load myjobs.json -d myjobs ./photonIdAnalyzer.py maxEvent=100

# submit all jobs. add -q <queue_name> to run in batch
fggRunJobs.py --load myjobs.json -d myjobs -H -D -P -n 5 ./photonIdAnalyzer.py maxEvent=-1

Configuration files

Analysis/config/high_mass_analysis.py: full analysis with signal region and sidebands.
Analysis/config/regressionTreeAnalyzer.py: regression training tree producer.
Analysis/config/photonIdAnalyzer.py, Analysis/config/photonIdDumper.py: photon ID training tree producer.

JSON files containing list of processes.

Analysis/config/jobs_gamgam.json : only GGJets sherpa
Analysis/config/jobs_gamjets.json : only GJets madgraph
Analysis/config/jobs_gamjets_gamgam.json : all processes

Macros

Macros are stored in Analysis/macros.

They tipically come with associated JSON file for configuration. Python macros are run as: ./macroName.py --load macroConfig.json [additional options, typilcally --input-dir <input dir> -O <output dir>]

The --help option gives a list of supported options, while the --dumpConfig dumps all options in JSON format (useful to record a particular configuration).

Analysis/macros/idEvolution.py: photon ID studies. Runs on the output of Analysis/config/photonIdAnalyer.py or photonIdDumper.py.
Analysis/macros/basic_plots.py: basic di-photon plots. Runs on the output of Analysis/config/high_mass_analysis.py.
Analysis/macros/eff_plots.py: efficiency for di-photon selection. Runs on the output of Analysis/config/high_mass_analysis.py.
Analysis/macros/templates_maker.py: deals with templates creation.
