Hey guys!

I have a problem when running my analysis.
I try do do a simulation using the Event Generator developed by Manuel Zambrana, wich is included in PandaRoot and available to everybody.
To do that I followed the instructions of Dmitry Khaneft, and I manage to do the simulation, digitization, reconstruction and particle identification. But when I run the analysis I get the next Warning and then it crashes

************************************************************* 
     initialisation for run id 1398851978
************************************************************* 
-I- FairRunTimeDB::InitContainer() FairGeoParSet

[INFO   ]  Branch: PidAlgoMvd  not found in Tree  
Warning in <PndAnaPidCombiner::PndAnaPidCombiner::ReadTCA()>: No "PidAlgoMvd" array found.

 *** Break *** segmentation violation

I don't want to start copying all my simulation and analysis code, and it looks like the problem comes from the PID macro... but I'm not sure about it.
Can I get any hints/help to solve the problem?

The same analysis works for another e+e- event generator, without problem, and I didn't change anything from the digi, reco, pid macros...
I'm a bit lost...

Thanks in advance

Can you open the pid_complete.root and check from the TBrowser that PidAlgoMvd is written there?
And could you check if in pid_complete.C the following lines are included and not commented out:

  PndPidMvdAssociatorTask *assMvd= new PndPidMvdAssociatorTask();
  fRun->AddTask(assMvd);

Thanks Stefano,

I tried to read the file with the TBrowser, the PID branches were all not saved.

I found the origin of the problem, I was reading the wrong input file in one of the steps... (My fault Embarassed

) It took me some time to find out, but now It finally works.
Thanks again for your help, and sorry for the inconveniences.
