  • If Athena reconstruction stops running after ESD production, but before AOD production with this unbuffered output below, then you've either run out out of disk space, or have done previously in an earlier run. Remove all files that reconstruction produces and try again!

  • browse and copy with rfcp and rfdir
  • copy files with xrdcp : xrdcp root://castoratlas//castor/cern.ch/grid/atlas/atlasscratchdisk/your_file_name /tmp/your_file_name
  • Castor twiki page
  • CAF twiki page
  • for atlcal pool first do export STAGE_SVCCLASS=atlcal
  • then you can do (file by file) rfcp /castor/cern.ch/grid/atlas/caf/atlcal/perm/trigger/data11_7TeV/physics_EnhancedBias/00178044/data11_7TeV.00178044.physics_EnhancedBias.hltmerge.AOD.c580_c583_m274/data11_7TeV.00178044.physics_EnhancedBias.hltmerge.AOD.c580_c583_m274._0028.1 .
  • check a file is staged first by doing stager_qry -S atlcal -M /castor/cern.ch/grid/atlas/blah... and remember you cannot stage files on atlcal pool

Getting jobOptions and other files

  • get_files CSC.005118.JimmyZmumuLowM_onelep.py
  • get_files checkFile.py
  • get_files checkTrigger.py

Links and Tips for Viewing Code

Examining files

  • to tell if a file is ESD or AOD etc: checkFile.py YourAODorESD.pool.root
  • to find the geometry version: dumpVersionTags.py yourESD.pool.root


  • use vp1 to visualise the experiment and data (not atlantis). After doing std athena setup just run vp1 on the commandline and play with the gui, optionally give it a root filename argument to read data from


  • create XML files by running athena and using ESD or AOD jobOptions files:
    athena AtlantisESD_jobOptions.py or athena AtlantisAOD_jobOptions.py at QM
    Make sure you set the correct geometry tag in the jobOptions
  • then at QM run atlantis on the XML files like so:
    /usr/bin/java -jar  /afs/cern.ch/atlas/project/Atlantis/current/atlantis.jar  tag


  • run < parameter.txt read steering from file
  • run 1 2 supply command line arguments
  • break main break at line 1
  • break pylist_ break in routine pylist
  • break pyrand.f:60 break at line 60 of pyrand.f
  • step one line at a time; steps *into functions*
  • next as above but executes entire funtions
  • finish continues till end of currect function
  • cont continue till next breakpoint
  • whatis
  • where
  • list
  • info breakpoints list all breakpoints
  • tbreak 110 temp breakpoint active once
  • kill stop program, can restart again
  • delete 2 delete breakpoint 2
