What it is

How to get it?

IMPORTANT: For now this is a combination of two packages, if one of them changes, the following procedure will work any more, I will try to keep this page updated, but if you run into trouble, let me (Sarah Heim) know!
  • check out LeptonX package
    export SVNROOT=svn+ssh://sheim@svn.cern.ch/reps/atlasgrp
    svn co $SVNROOT/Physics/Exotic/LeptonX/Tools/trunk/ntDumper 
    (your username instead of sheim)

  • go to ntDumper/PhysicsAnalysis/AnalysisCommon and do
    mv myAna myAnaOLD 
  • check out MSU package
    svn co $SVNROOT/Institutes/MSU/MSUHighPtElectrons/ntDumperMSU/myAna/trunk/ myAna
  • in ntDumper
    mkdir Output 
    source  /afs/cern.ch/sw/contrib/CMT/v1r20p20090520/mgr/setup.sh
    cmt config
    source setCMT.bash
  • in TestRun
    cp ../PhysicsAnalysis/AnalysisCommon/myAna/run/* . 
  • in TestProject/cmt
    cmt config
    cmt bro make clean
    cmt bro make

How to run it?

  • go to the TestRun directory
  • open the job options file there and edit if you want to run on AOD or ESD, also set analysis flags (mainly which particles you want to run on, trigger, truth?)
  • also change the output location and the input files
  • athena.py ...joboptions.py

On the grid?

export PATHENA_GRID_SETUP_SH=/afs/cern.ch/project/gd/LCG-share/current/etc/profile.d/grid_env.sh
source /afs/cern.ch/atlas/offline/external/GRID/DA/panda-client/latest/etc/panda/panda_setup.sh
pathena sheim...joboptions.py --inDS user10.SarahHeim.bla --outDS user10.SarahHeim.bla 
To get datasets/output from grid:
source /afs/cern.ch/atlas/offline/external/GRID/ddm/DQ2Clients/setup.sh
dq2-get bla

How to compile?

  • in ntDumper
    source setCMT.bash
    (really necessary?)
  • in TestProject/cmt
    cmt config
    (really necessary?)
    cmt bro make clean
    cmt bro make

What to change between running on data and MC?

  • DetDescrVersion (right now ='ATLAS-GEO-08-00-02' ) => info from AMI
  • #GlobalFlags.DetGeo.set_atlas() ???
  • GlobalFlags.DataSource.set_data() ##processing Real Data #
  • GlobalFlags.DataSource.set_geant4() ##processing MC
  • for running on data: doTruth and doTruth2 have to be FALSE

Structure of package

Job Options

  • general job options (one for AOD, ESD...)
    => can pick which particles want to run over, can pick things like DoTrigger, picks the right special job options, algorithms
    => uses Analysis.Flags (?)
    => also something called doAOD, doESD


  • DoParticles is specializes into p.ex. DoElectrons, here the variables are filled
  • DoTrigger fills branches for different trigger chains: if event passed=>1, if not=>0
  • DoL1ROI fills branches with eta, phi... of different region of interests
  • DoTruth does fill branches with thruth info from MC (uses egammaMCTruthClassifier and muonMCTruthClassifier)
  • DoTruth2 does fill branches with truth information from MC, also does a lot top, antitop, W, Z stuff

What would we want to change

  • add our variables (in case they are not there yet) DONE
  • What about trigger information? DONE
  • we only need Electrons and MET? Photons? Trigger/Truth? OK
  • add Lumiblock and GoodRunListInfo

How to add a new algorithm?

  • example DoEgammaESD
  • add src, header file
  • add in src/components
  • add job options file in share
  • add Flag in python
  • add to general and analysis job options file
  • compile!

How to add a new variable?

  • in header as vector
  • in src as branch, clear, fill


Useful information:

  • cross section that is used in MC production can be found in evgen.log which is in the MC09....evgen.... directory.
    With the cross section and the number of generated events, one can calculate the available luminosity L = N/sigma.
    With the cross section, one can get the number of events for a chosen luminosity (all integrated luminosities here). N = sigma * L
