Hi,
I met one problem when run reconstruction algorithms.

I once printed out lots of informations and found that this is caused by some abnormal momentum,(like 1e-346...)
I have tried to modify FairTrackParP.cxx to discard this kind of events. But this is not a good solution.
Pls tell me if this has been solved.

Thanks

Hi,
could you please add the following line in PndLheTrackFitter, so that I can see which numbers are giving problems?
In particular, please add at line 220 (before if (ih==0)):

cout << ih << "\t" << track->GetCharge() << "\t" << x << "\t" << y << "\t" << z << "\t" << px << "\t" << py << "\t" << pz << endl;

So that I can try to guess what is going wrong at the track when the code is crashing. I have never seen such kind of error.

Many thanks.

I think you should update the whole trunk. Maybe you have a version of the code without the implementation of the MultiLinkData

Good!
Could you please edit the first message, putting a [FIXED] before the title?
Thanks.
