ECAL Local reconstruction in CMSSW for Phase 2

Where:

/home/amassiro/Cern/Code/UniMiB/ECALLocalRecoPhase2

Instructions to install CMSSW, prepare code, make PRs, ...

Install, after logging to lxplus

cmsrel  CMSSW_11_2_0

cmsrel installs cmssw, and the needed links, but it does not actually downloads packages. they will be needed to be downloaded later on.

cd CMSSW_11_2_0/src/

Code goes to "src" folder.

cmsenv

cmsenv allows you to compile and run code in this selected cmssw release

git-cms-addpkg  Configuration/PyReleaseValidation/

git-cms-addpkg downloads in local that package. Then you can modify that package and compile

To compile, always go to the main "src" folder and run

scramv1 b -j 20

Details

git-cms-addpkg  Configuration/PyReleaseValidation/
git-cms-addpkg  SimCalorimetry/EcalSimProducers/

From Stefano's instructions

cp /afs/cern.ch/user/a/argiro/public/ph2Reco/EcalLiteDTUPedestalsESProducer.cc SimCalorimetry/EcalSimProducers/    

scramv1 b -j 20

Test

runTheMatrix.py -w upgrade -l 28234.61

cd 28234.61_TTbar_14TeV+2026D60_ecalDevel+TTbar_14TeV_TuneCP5_GenSimHLBeamSpot14+DigiTrigger+RecoGlobal+HARVESTGlobal/

cmsRun TTbar_14TeV_TuneCP5_cfi_GEN_SIM.py

-> in step2_DIGI.py add

    process.GlobalTag.toGet = cms.VPSet(
      cms.PSet(record = cms.string("EcalSimPulseShapeRcd"),
        tag = cms.string("EcalSimPulseShapePhaseII"),
        connect = cms.string("frontier://FrontierProd/CMS_CONDITIONS")
      )
    )

Reconstruction step

git-cms-addpkg  RecoLocalCalo/EcalRecProducers
git-cms-addpkg  RecoLocalCalo/EcalRecAlgos

Try simple max-amplitude algorithm. Then move to weights based reconstruction.
