---+++ Data

A local copy of xAOD input data is here:

---+++ xAOD EDM Notes

[[https://twiki.cern.ch/twiki/bin/view/AtlasComputing/SoftwareTutorialxAODEDM][Original twiki page]]

Mostly this worked for me, but in the section PyROOT with the xAOD note that:
   * You have to setup the analysis release to get this to work (setupATLAS; rcSetup 2.0.3,Base)
   * The example does run but reports errors at the end

---++++ Section 3
   * The path to make_skeleton didn't work for me ($ROOTCOREBIN was pointing to my local setup area). Instead I needed to run it as:
      * =$ /cvmfs/atlas.cern.ch/repo/sw/ASG/AnalysisBase/2.0.3/EventLoop/scripts/make_skeleton gsAnalysis !MyxAODAnalysis=
---++++ Section 5
   * You can use the samples here:
      * =SH::scanDir(sh, "/afs/phas.gla.ac.uk/user/g/graeme/public/xAODtut/");=
   * Note that if you get something wrong, then try to re-run the code will crash as the output directory exists (it doesn't like that):
      * =EventLoop:/build3/atnight/localbuilds/nightlies/AnalysisBase-2.0.X/AnalysisBase/rel_nightly/EventLoop/Root/Driver.cxx:94:exception: could not create output directory /afs/phas.gla.ac.uk/user/g/graeme/xAODtut/Run/submitDir=
   * Running both the ROOT macro and the standalone testRun.cxx gave unchecked status code warnings (1 for each file)
---++++ Section 6
   * To get the jets package compiled and linked properly to testRun, I needed to do an rc clean as well as find_packages and compile.
---++++ Section 7
   * Comiplation errors when comiling =testRun.cxx= (comlaints about a forward declaration in <span class="WYSIWYG_TT">SampleHandler.h</span>). Haven't had time to dig into these yet.
