Hi all,

when trying to run Dima's reconstruction macro I get the following reproducible crash after several events:

Is anyone aware of what's going wrong there? I can see this is connected to the FairLinks somehow, but for the tpc code we disabled all usage of the links due to persistent problems in the past...


Thanks in advance

Felix

Which trunk are you using? Yesterday I was able to run 500 evt with tpc/eta_c w/o problems.

Hi Stefano,

I'm using revision 12501. Should I downgrade? To which revision?


Cheers

Felix

In reality I have just tried with the latest trunk and it seems to work, in my case.
However, maybe I have understood the problem.
In PndTrackCand, links are set in the AddHit functions:

AddLink(FairLink(detId, hitId));


The problem I can see here is that you are using the old detId definition, based on the PndDetectorList enum, and not the current one:

UInt_t detId = ioman->GetBranchId(branchName);


Maybe in FairLink the code is trying to find a branch defined by a "mispaced" detId -> crash.

In your local case, you could comment out the lines with AddLink of PndTrackCand.cxx.
I repeat, if you want I can spend some time on your tracking tasks to be compatible with the branch id definition. Just tell me, so that you can work on other tracking points.

Actually, I would appreciate this very much! Thanks!

Hi,
I have modified (in svn) the code in tpc/tpcreco and recostasks, so now it is compatible with the branch id.
I order to check the code, I have run Dima analysis with the old code and the new one, and the eta_c histograms are exactly the same.

The followings are the modified files:

M       tpc/tpcreco/PndTpcRiemannTrackingTask.cxx
M       tpc/tpcreco/PndTpcGEMCorrelatorTask.cxx
M       tpc/tpcreco/PndTpcdEdxTask.cxx
M       tpc/tpcreco/PndTpcMVDCorrelatorTask.cxx
M       recotasks/KalmanTask.cxx



I ahve also modified the DEBUG flag. Now the "debug" couts are called setting the verbose level in the task !=0 ->

tpcriemanntask->SetVerbose(1);


To reduce a bit the log messages, even if the ones from low momenta tracks are still many.

Now it should be possible to use the normal MCTrackAssociator and also the mvd de/dx.. but the latter I have to check.
Please let me know if it crashes again.
