PAT Release Notes (compatible with CMSSW_3_4_X)

Warning, important From CMSSW_3_4_0_pre4 on, CMSSW_3_4_X should, from CMSSW_3_4_0_pre6 on must be used with SLC5. To do so, use

$ ssh

Please use main trunk for CMS.PhysicsTools/PatAlgos, CMS.PhysicsTools/PatUtils, CMS.PhysicsTools/Utilities, and CMS.PhysicsTools/PatExamples. This is the "new feature" release and any other new features can only be backported to older releases with the coordination of the PAT development team.

Please follow the tag conventions here:

CMS.PhysicsTools/PatAlgos V07-10-zz
CMS.PhysicsTools/PatUtils V03-09-zz
CMS.PhysicsTools/PatExamples V00-01-zz
CMS.PhysicsTools/Utilities V07-02-zz


  • added two more files in test directory to demonstrate how to run pf2pat on data.
  • moved genMet edm::InputTag from genMetCalo to genMetTrue (on request of pflow).
  • added a tag of DataFormats/PatCandidates to the list of tags including the following:
    • extension of tau getter functions.
    • extension of jet getter functions.
    • doxygen documentation.

  • removed patch of L7 correction from as it is not needed any more.


  • adding the collection name they are acting on to the name of the corresponding userIsolationTools for electrons, muons and photons.

  • removeMCMatching now takes a list of string instead of a string.
  • added three tools to re-add predefined sets of userIsolation for electrons, muons and photons.


  • allow trigger tools to run on 'all' and 'selected' objects (in addition to 'clean' ones).


  • removed fragile infrastructure for running PF2PAT and PAT in parallel.
  • back port of cloneProcessingSnippet.


  • removed re-reco'ed files.

  • Also the rest of the AT integration packages are including, JPT updates and Type 1 MET updates.

  • straightening of all changes in the B3_4_X branch.
  • a bit of cleanup in test files for single object collection tests.
  • a minor extension in EventContent automatically to write added jet/met collections to file.
  • NB: the rereco09 test file misses some proper input file (this will be fixed soon).

  • Fix of conflict between FastSim and PAT when running in the same job.



  • Cleanup of pat default sequences.
  • update of input files in patTemplate.
  • removed switchJetCollection from patTemplate as it is not needed anymore from 34X on.
  • Fixed bug in JetIDSelectionFunctor

V03-09-08-03   PhysicsTools/PatUtils 
V07-04-00-01   PhysicsTools/Utilities

V07-10-05 (Identical to 3.4.1)

  • Removed MC dependencies for PF2PAT.


  • Added configurations to run over 900 GeV and 2360 GeV 341 re-recoed samples. Otherwise identical to 341. Requires the addition of these tags:

V01-08-08-09   CondFormats/JetMETObjects                        
V01-08-23-05   JetMETCorrections/Configuration   


  • Adaption of trigger object types.


  • Adaption to upstream changes in the MET Significance algorithm.
  • New PF jet interface to access constituents via CandidatePtr.
