hello Ajay,
please go to the new version of the pattern recognition that is better debugged.
In your Macro, instead of the lines :
// PndSttTrackFinderIdeal* sttTrackFinder = new PndSttTrackFinderIdeal(iVerbose);
PndSttTrackFinderReal* sttTrackFinder = new PndSttTrackFinderReal(0);
PndSttFindTracks* sttFindTracks = new PndSttFindTracks("Track Finder", "FairTask", sttTrackFinder, iVerbose);
sttFindTracks->AddHitCollectionName("STTHit", "STTPoint");
//sttFindTracks->SetPersistence(kFALSE);
fRun->AddTask(sttFindTracks);
PndSttMvdTracking * SttMvdTracking = new PndSttMvdTracking(0, false, false);
//SttMvdTracking->Cleanup();
SttMvdTracking->SetPersistence(kFALSE);
// SttMvdTracking->SetPersistence(kTRUE);
fRun->AddTask(SttMvdTracking);
replace them by the following lines :
// Unified Pattern Recognition
// use the constructor with input :
// printout flag (int) , plotting flag (bool), MC comparison flag (bool),SciTil.
PndTrkTracking* tracking = new PndTrkTracking(0,false,false,false);
tracking->SetInputBranchName("STTHit","MVDHitsPixel","MVDHitsStrip ");
// tracking->SetInputBranchName("STTHitMix","MVDHitsPixelMix","MVDHitsStripMix ");
// don't do the Pattern Recognition second part, starting from the Mvd;
tracking->NoMvdAloneTracking();
// do Cleanup only when there is Mixing;
// tracking->Cleanup();
fRun->AddTask(tracking);
NOTICE that the last false in
............ = new PndTrkTracking(0,false,false,false);
^

prevents the use of the SciTil information. This is so because of the present conflict existing between the geometriy of the DIRC and of the SciTil (in other words : if you use the DIRC geometry you will not get the SciTil points because
of an apparent overlap of the two geometries).
IN CASE YOU DON'T HAVE THE DIRC geometry you can instead use the 'true' in the constructor :
........... = new PndTrkTracking(0,false,false,true);
Please let me know if everything works, thanks@!

Hi all,
I am getting a crash in my reco macro(pandaroot/macro/pid) when trying for 100000 events.I have runed two time my reco macro,every time reco task crashed after 36 events.Then I tried by skiping this event no.36 like as:-
fRun->Run(0,35);
fRun->Run(37,100000);
Again it goes to same crash after 389 events.I have attached the reco macro & crash error file here.
After run in gdb debugger i got-:
Found Tracks: 2 in event no. 35
----------------
Found Tracks: 1 in event no. 36
----------------

can anybody help me?
Thanks in advance.
