Reading Testbeam files

  • Prepare your setup:
    • setup your environment:
      cd /afs/cern.ch/cms/Releases/CMSSW/CMSSW_0_8_0/
      eval `scramv1 runtime -sh`
      cd -
    • start root:
      root
    • load fwlite:
      gSystem->Load("libFWCoreFWLite.so")
      AutoLibraryLoader::enable()

  • Some plots for the simhits file above:
    • Simulated energy (needs to be checked by an expert but produces reasonable distributions):
      Events->SetAlias("simhit","PCaloHits_SimG4Object_EcalHitsEB_PROD.obj")
      Events->Draw("simhit.energy()","simhit.energy()>5")

  • Produce rechits from the digis contained in the file (assumes that you have the file in your local directory):
    cmsRun -p digitize.cfg
    (download digitize.cfg )

  • Produce clusters (and superclusters) from the rechits file:
    cmsRun -p egammaRecHitsToClusters.cfg
    (download egammaRecHitsToClusters.cfg, based on RecoEcal/EgammaClusterProducers/test/egammaRecHitsToClusters.cfg of CMSSW_0_8_0)
    • make some plots (using ecal_TB_clusters.root):
                gSystem->Load("libFWCoreFWLite.so"); AutoLibraryLoader::enable(); new TFile("ecal_TB_clusters.root"); new TBrowser;
                Events->SetAlias("clusters","recoBasicClusters_islandBasicClusterProducer_islandBarrelBasicClusterCollection_egammaRecHitsToClustersProcess.obj");
                Events->Draw("clusters.energy()");
