Hello,
I wanted to reconstruct some tracks using lhetrack+genfit, using TPC+MVD.
I have run the macros in macro/pid, exactly:

root run_sim_tpccombi_pgun.C"(500,13,1)"
root run_digi_tpccombi.C
root run_reco_tpccombi.C 


and after a while I get a crash coming from the kalman.
I have modified a bit the class PndLheKalmanTask.cxx in order to have some cout, and this is the error output:

Toggle Spoiler


The initial parameters are, in red: position, momentum, position error, momentum error -> a not so special track.
This track is made of 6 hits, it seems only MVD hits. At the end the error seems in TGeant3::Ertrak () .

If somebody could take a look and hopefully fix it...
Thanks in advance
