External software

• ROOT_version = "6.22.02-3"

Packages changed wrt. to v02-02-MC

• MarlinTrkProcessors → v02-12-MC
  • Double-layer filtering + Splitting by layers
    • Introduces a new FilterDoubleLayerHits processor for filtering of RecHits based on their angular alignment within a double-layer.
    • Updates the SplitCollectionByLayer processor to support custom layer combinations.
  • Extra quality cuts in Refitter
    • Minimal Chi2/NDF

• ConformalTracking → v01-11-MC
  • Added timing histograms for each tracking step
  • Added support for excluding collections used for initial seed hit creation. Added per-step debug histograms
  • Separated step debugging plots with an own configuration parameter
• lcio →v02-15-04-MC
  • fix nan's in jet 4-momenta (delphes2lcio)
  • delphes: fix PDG in PID objects of neutral hadrons
  • add optional extra PFO collections in delphes2lcio
  • Python3 compatibility of Reader class

Know problems

1. The path of the geometry in the MuonCutil/confile/* are wrongs.
   1. Use the correct ones: /opt/ilcsoft/v02-03-MC/detector-simulation/geometries/MuColl_v0/MuColl_v0.xml
2. Default value for ddsim is to use HepMC3 Helper reader which is not supported by now. 
   
   1. You can use the command line option for ddsim: --hepmc3.useHepMC3 false or put SIM. hepmc3.useHepMC3 = False in your sterring file
3. Using hepmc input file for ddsim produces a fatal exception likes this one:

   G4DecayTable::SelectADecayChannel :: no possible DecayChannel mu+
   
   -------- EEEE ------- G4Exception-START -------- EEEE -------
   *** G4Exception : DECAY003
   issued by : G4Decay::DoIt
   Can not determine decay channel for mu+
   mass of dynamic particle: 0.00010566 (GEV)
   dacay table has 1 entries
   0: BR 1, IsOK? 0, --> e+ + nu_e + anti_nu_mu
   
   *** Fatal Exception *** core dump ***

   1. At the moment the only workaround is to downgrade the version of DD4Hep from v01-14 to v01-13-01
