Hi!
If I run the demo and try to use geane with the kalman filter I get the following error. Somehow a 0 momentum is appearing. It appears to me to be inside CbmGeanePro, since in geaneTrackRep the values look alright. I am not sure where the bug is.
Could anyone try to reproduce this, please!
*** S/R ERPROP IERR = 2
*** Error in subr. TRPROP 2 called bysubr. ERPROP
Program received signal SIGFPE, Arithmetic exception.
