CMS ECAL Timing Calibration directory

1. Install:

   • scram project CMSSW_10_0_3
   • cd CMSSW_10_0_3
   • cmsenv
   • git cms-addpkg CondTools/Ecal
   • git clone [email protected]:bmarzocc/EcalTiming.git
   • cd EcalTiming
   • git checkout Run2018
   • cd -
   • cp EcalTiming/EcalTiming/interface/EcalFloatCondObjectContainerXMLTranslator.h CondTools/Ecal/interface/
   • rm EcalTiming/EcalTiming/interface/EcalFloatCondObjectContainerXMLTranslator.h
   • cp EcalTiming/EcalTiming/src/EcalFloatCondObjectContainerXMLTranslator.cc CondTools/Ecal/src/
   • rm EcalTiming/EcalTiming/src/EcalFloatCondObjectContainerXMLTranslator.cc
   • cp EcalTiming/EcalTiming/test/testEcalTimeCalib.py CondTools/Ecal/python/
   • rm EcalTiming/EcalTiming/test/testEcalTimeCalib.py
   • scram b -j 5

2. Run local:

   • cd EcalTiming/EcalTiming/
   • cmsRun test/ecalTime_fromAlcaStream_cfg.py files=root://cms-xrd-global.cern.ch//store/data/Commissioning2017/AlCaPhiSym/RAW/v1/000/293/910/00000/181C8C47-8237-E711-9089-02163E0118FF.root globaltag=90X_dataRun2_HLT_v2
   • NOTE: the outputs are produced in one step and CANNOT BE MERGED with other outputs.

3. Run on parallel (using LXBATCH):

   • launch 1st step (ntuple step):

     • cd EcalTiming/EcalTiming/lxbatch/
     • voms-proxy-init --voms cms --valid 168:00
     • perl launchJobs_lxbatch.pl params_lxbatch.CFG
     • sh lancia.sh

   • Parameters settings in "params_lxbatch.CFG":

     • BASEDir: absolute path of the lxbatch directory
     • X509_USER_PROXY: path of the proxy (before launching better do: export X509_USER_PROXY=/afs/cern.ch/work/X/XXX/x509up_XXX)
     • JOBCfgTemplate: name of the python to launch
     • DATASETName: name of the dataset to be run
     • INPUTRuns: input runs
     • OUTPUTSAVEPath: path of the output files (EOS directories as default)
     • OUTPUTFILEName: name of the output file.root
     • QUEUE: lxbatch queue
     • JOBdir: directory to store job directories
     • JSONFile: json file
     • GT: gloabl tag

   • launch 2nd step (calibration step):

     • cd EcalTiming/EcalTiming/lxbatch/
     • voms-proxy-init --voms cms --valid 168:00
     • perl launchJobs_lxbatch_calibStep.pl params_lxbatch_calibStep.CFG
     • sh lancia.sh

   • Parameters settings in "params_lxbatch_calibStep.CFG":

     • BASEDir: absolute path of the lxbatch directory
     • JOBCfgTemplate: name of the python to launch
     • INPUTDir: directory of input runs (output of the 1st step)
     • INPUTRuns: input runs
     • OUTPUTSAVEPath: path of the output files (EOS directories as default)
     • QUEUE: lxbatch queue

4. Produce the sql tag file:

   • The output of the calibration needs to have the following name format:

     • eg: ecalTiming-corr.dat -> ecalTiming-corr_2017_09_26.dat

   • Produce the absolute time calibration (xml file) from the latest IOV:

     • cd EcalTiming/EcalTiming/test/
     • eg: python makeTimingXML.py --tag=EcalTimeCalibConstants_v01_express --inList=input_List_2017.dat
     • eg: python makeTimingXML.py --tag=EcalTimeCalibConstants_v01_express --calib=/eos/cms/store/group/dpg_ecal/alca_ecalcalib/EcalTiming/Run2017E/Calibration/303948/ecalTiming-corr_2017_09_26.dat
     • eg: python makeTimingXML.py --payload=2cc0da4e6a1ec506d037aa476e76bca8ac9ab9fb --inList=input_List_2017.dat
     • eg: python makeTimingXML.py --payload=2cc0da4e6a1ec506d037aa476e76bca8ac9ab9fb --calib=/eos/cms/store/group/dpg_ecal/alca_ecalcalib/EcalTiming/Run2017E/Calibration/303948/ecalTiming-corr_2017_09_26.dat

   • Produce the sqlite file from the absolute timing xml file:

     • cd EcalTiming/EcalTiming/test/
     • eg: python makeTimingSqlite.py --calib=/eos/cms/store/group/dpg_ecal/alca_ecalcalib/EcalTiming/Run2017E/Calibration/303948/ecalTiming-abs_2017_09_26.xml --tag=EcalTimeCalibConstants_Legacy2017_v1
     • eg: python makeTimingSqlite.py --inList=input_List_2017_absTiming.dat --tag=EcalTimeCalibConstants_Legacy2017_v1
     • sh launch_tagCreation.sh

5. Make history plot:

   • cd EcalTiming/EcalTiming/test/
   • eg: python makeHistoryPlot.py --tag=EcalTimeCalibConstants_v01_express --year=2017
   • eg: python makeHistoryPlot.py --inList=input_List_2017.dat
   • eg: python makeHistoryPlot.py --inList=input_List_2017.dat --runBased
   • eg: python makeHistoryPlot.py --inList=input_List_2017_RunE.dat --epoch=E
   • eg: python makeHistoryPlot.py --inList=input_List_2017_absTiming.dat --absTime
