This page documents the details of the common xAOD ntuples for the VV exotic analysis at University of Edinburgh.

Instructions and developments


  • Please contact either Ben Wynne or Yanyan Gao for comments/questions
  • Instructions: VVXAOD README
    • Default: AthAnalysisRelease
        • 20.7, supports tag since VXAOD-00-00-44 and trunk
        • 20.1, supports tag up to VXAOD-00-00-43
    • Option of Derivation release, only use this if you need to remake the fat jets
      • Latest tag VVXAOD-00-00-16, matching share/
      • do not support trunk, make sure put the right tag in the installation script before executation
  • See the ChangeLog for the details of changes.

On-going developments for release 20.7

Instructions on the PC recommendations link to release 20 recommendations

  • electron and photon
  • muons
    • calibrations
    • selections
    • efficiency scale factors
  • MET Met20p7
  • small R jet calibrations
  • large R jets JetMet2016
    • recommendations have not available yet
  • jet cleaning
  • overlap removal, implemented but not yet tested
  • b-tagging
    • btag recommendation
    • need to use MV2c10 instead of MV2c20 (change in the configuration file is needed)

Notes for developers

Please stick to these procedures for bookkeeping.

  • Any change on the trunk must be tagged
  • For a new tag make sure the following changes are applied
    • Document the changes in ChangeLog
    • Update version in cmt/versions
    • Update version at the top of the src/TestAlg.cxx
  • Example for tagging command (note does not work for institute code for some reason)
svn cp svn+ssh:// svn+ssh:// -m "loverly comments"
  • Any new release must be paired with installation script, see example:
  • Before checking out a specific tag check the version of the package in the release by -s PACKAGE. If the version in the release is higher than the recommended, do nothing.

Special instructions for Edinburgh PPE machines

Before doing any asetup commands on the PPE machines you have to asetup an old release first. I do not know why. Try something like this:

asetup 17.8.0,here asetup WhatYouActuallyWanted,here

More on running locally at PPE machines:

List of files on ECDF (this should be changed to the FAX method but those paths don't seem to work with athena at the moment while this does. )

dq2-ls -f -p -L UKI-SCOTGRID-ECDF_LOCALGROUPDISK mc14_13TeV.147914.Pythia8_AU2CT10_jetjet_JZ4W.recon.AOD.e2743_s1982_s2008_r5787/ |  grep srm | sed 's/srm:\/\/\/\/\//g' > xrootdfilelist
voms-proxy-init -voms atlas --valid 48:0
cd VVAnalysis/
asetup 17.0.2,slc5,here
asetup 19.2.0,here
cd VVXAOD/share/

Execute over all the files in the list. For this changed to svcMgr.EventSelector.InputCollections = [os.getenv('FNAME’)] (athena -c ‘FNAME=$line’ also probably works)

while read line ; do export FNAME=$line ; athena >& /Disk/ecdf-nfs-ppe/atlas/users/wbhimji/xAODOutputs/`echo "$line" | cut -d '.' -f 11`.log; mv output.root /Disk/ecdf-nfs-ppe/atlas/users/wbhimji/xAODOutputs/`echo "$line" | cut -d '.' -f 11`.root; done < ~/xrootdfilelist
