Running the Code

Analysis is done in several steps:

  • patTuples from AOD -> ntuples from patTuples -> reduced ntuples (skimming and trimming) -> plots from ntuple -> (fits from plots/further reduced ntuple)


For data, PatTuples are made using For MC, PatTuples are made using

To test either locally, change the PoolSource file names to an AOD file (at UW), and PoolOutputModule output file name to something stored on the local scratch space (the patTuples are very large files). Don't forget to change back before submitting crab or farmout jobs. Farmout jobs take $inputFileNames and $outputFileName. Crab jobs have empty input files, and any desired output name (no slashes).

There is HLT filtering at this stage, but the total event counts before and after the filter are stored. You can also remove the filter by commenting out the line process.hltHighLevel *

PatTuple files go to dcache and can then be run on to create ntuples


For data, ntuples are made using For mc, ntuples are made using

Both data and MC can be submitted using farmoutAnalysisJobs. Again, to test locally, change the PoolSource to one of that patTuples made in the previous step. Change $outputFileName in the line process.VplusJets.HistOutFile = cms.string('$outputFileName') to desired output name.

This is where the code in UserCode/grogg/src is used. Two configuration files in the /python directory are used.


The skimming/trimming/merging is done all at once.

  • Ntuples stored on dcache need to be copied over to a local scratch area using merge files (syntax specified in
  • In /test open root
  • The branch selector/skimmer needs to be modified to ones needs
    • This will loop over whatever samples you want, and add branches with event weight and a number (e.g. W MC is "0" and Z MC is "1")
      • Desired cross section must be specified. If any events were skimmed out at the pattuple stage, these need to be accounted for:
        • Merge just the histogram in all the ntuple files: hadd -T sampleName_hist.root [sampleName]
        • root sampleName_hist.root //open file with just numEvents histogram
        • numEvents->GetBinContent(6) / numEvents->GetBinContent(1) //get the final number of events divided by the initial number. The cross section needs to be multiplied by this number
    • Add/remove branches as necessary by setting the branch status to 0 or 1 (all are set to zero initially, so only those explicitly set to 1 are kept).
    • Skimming is done on this line: TTree *newTree = oldtree->CopyTree("hltAccept==1 && (PfW_electron_pt>10 || CaloW_electron_et > 10)")
      • In this case only events that pass the HLT and have a gsf ("Calo") or pf electron above a pt of 10 make it into the final ntuple (the inital and final number of events are printed after merging)


  • Code is in UserCode/grogg/macros
  • Base class for running over MC and data: WenuJetsBase.C
    • This is compiled when root starts using a line in rootlogon.C: gROOT->ProcessLine(".x WenuJetsBase.C+");
  • Sub classes for various tasks include WenuJetsAnalyzer.C, WenuJetsFit.C, WenuJetsJetStudies.C, WenuJetsRooUnfold.C, WenuJetsAbcd.C
  • The lines to run each of these tasks is given above the Loop() function in each file, e.g. nohup root -q -b "WenuJetsAnalyzer.C+(0, \"WJets\", 0)" > Wlog &
    • Some are run by MC/data type, some need to run over all MC/data at once, and this is indicated by a name, e.g., "WJets", or "all"
  • Additional macros are available for plotting from the results of these codes, as well as doing fitting
  • Basic plots can be made using Jeff's rootplot program: e.g., rootplot DataInclusive_36pb_gsfElec.root DataInclusive_36pb_pfElec.root --path=".*W_mt*"
  • Unfolding documentation can be found at RooUnfoldVJets


Running OLD Plotting Code


  • Use root on login01, the Summer09 datasets are in /scratch/grogg
  • To make basic plots run the following from /afs/
    • .L WenuJetsTree.C+
    • .x WenuJetsObjects.C+(0, "all", 0)
      • First argument is the tree used (should always be 0)
      • Second argument is the name given to the run, should describe what datasets were used an any special settings or cuts
      • Third argument is number of events to run over, 0 if running over all events
  • For electron specific plots (more detailed efficiency, S/B, ID and isolation)
    • .L WenuJetsTree.C+
    • .x WenuJetsElectrons.C+(0, "all", 0)
      • Same parameters as above
  • For plots comparing generator and reco objects
    • .L WenuJetsTree.C+
    • .x WenuJetsRecoGen.C+(0, "all", 0)
      • Same parameters as above
  • For background specific plots (ABCD, matrix, and file for fitting)
    • .L WenuJetsTree.C+
    • .x WenuJetsBackgrounds.C+(0, "all", 0)
      • Same parameters as above
  • For fitting:
    • First run WenuJetsBackgrounds.C, which outputs fitFile-*.root, where * is the name given in 2nd parameter
    • .x WenuJetsRooDataFit.C("fitFile-*.root", "1", 15, "w_Mt", 5, 20, false)
      • (string) fileName
      • (int) number of jets
      • (double) lower limit to fit
      • (string) variable type ("w_Mt" or "MET")
      • (int) number of pseudodatasets to run over,
      • (int) electron pt cut used
      • (bool) whether to vary the proportion of W events relative to background

Strange Errors

Do cmsRun, get this: python encountered the error: 'tuple' object has no attribute 'find'

  • Check for a comma after a proces.[stuff] entry
