Dear Dong,

please try to replace ioman->GetBranchId("MCTrack") with 0 as it is done in the next line of your code. I guess that it does not crash in that case.

The reason for the crash is, that the FairRootManager has not loaded the list of generated branches. Therefore no Id for "MCTrack" is returned.
Only if you use FairRunAna the branch list is populated in the FairRootManager.

Cheers,

Tobias
