Some Technicalities

EVNT to TRUTH1 (as of 2019-12-04)

This code below will transform a ATLAS EVGENT file to a TRUTH1 truth DxAOD derivation. Be patient. 10k events might take 10 minutes.

This is useful when you have rivet code you want to test against truth analysis code based on DxAOD

export ATLAS_LOCAL_ROOT_BASE=/cvmfs/atlas.cern.ch/repo/ATLASLocalRootBase
source ${ATLAS_LOCAL_ROOT_BASE}/user/atlasLocalSetup.sh
source $AtlasSetup/scripts/asetup.sh 21.2.55.0,AthDerivation,here
## truth ntuple
 Reco_tf.py --inputEVNTFile EVNT.root --outputDAODFile test.pool.root --reductionConf TRUTH1
 

Logbook

  1. 20180103: rel 21.2.13 Event/xAOD/xAODTracking/Root/TrackParticlexAODHelpers.cxx can have "TrackParticle with zero or negative d0 uncertainty." error.

    Solution: Try to catch that, set the d0sig for the muon to be -999, default value.
    Reason: if you require at least the lowest muon quality, this error will not appear. So retrieve d0sig for muons at certain WP.
