---++++CMKIN
   * Datacard parameters %BR%
     MSTJ(22)=2 %BR% A particle is decayed only if its proper lifetime is smaller than PARJ(71), which is set to c&#964; = 10 mm. Strange particles are "stable", charm and bottom decay.

---++++OSCAR
   * Simulate tracker only
      * Use reduced geometry file [[%ATTACHURL%/OSCARconfiguration.xml][%ICON{xml}%]]
   * Simulated V0 daughters
      * Mantis/MantisApplication: add to src/NewTrackAction.cc
<blockquote><verbatim>
#include "G4VProcess.hh"
// Lengths are in mm for OSCAR!
if( (aTrack->GetCreatorProcess()->GetProcessType() == fElectromagnetic &&
     aTrack->GetCreatorProcess()->GetProcessName() == "conv") ||
    (aTrack->GetCreatorProcess()->GetProcessType() == fDecay &&
     aTrack->GetCreatorProcess()->GetProcessName() == "Decay") )
  if(fabs(aTrack->GetPosition().z())    < 50. * 10 &&
     fabs(aTrack->GetPosition().perp()) < 15. * 10)
    trkInfo->storeTrack(true);
</verbatim></blockquote>
      * Mantis/MantisApplication: add to !BuildFile
<blockquote><verbatim>
 <use name=geant4>
 <use name=clhep>
</verbatim></blockquote>
      * compile in =Mantis/MantisApplication/src= %BR%
         =scramv1 build=
 
   * If an oscar job fails (exceeds the maximum cpu time, or loses terminal connection, etc), just copy the content of the =nameoftherun.runid= file (<verbatim>CARF:ResumeRun= @{[ ... a huge hexadecimal string ... ]}@</verbatim>)
 to the end of the =.oscarrc= file, and run again. The simulation should continue from the last successful event.

---++++ORCA
   * Compilation
      * !TrackerReco/PixelTrackFinder: add to src/SeedGeneratorByRecTracksRecAlgo.cc %BR%
      =#include "CARF/Reco/interface/RecConfig.h"=
      * !TrackerReco/TkEvent: add to interface/TkSimEventDispatch.h %BR%
      =#include "TrackerReco/TkEvent/interface/TkSimEvent.h"=
      * To skip cache scan: %BR%
      =scramv1 build --fast=
   * !SimTrack filtering
      * !TkEvent/src/SimpleCarfSimTrackFilter.cc: change the condition
      <verbatim>theSimTrack.charge() != 0</verbatim>
