Exactly how does the problem manifest? > The code segments faults inside the final HistOn() section in the BrTrackFinderBase :: FillDetectorTracks() Do you have this filling of deviation histograms. The code works just fine for TrackFollowFinder that walks through same piece of code. Maybe you could check the modifed Oslo version in, so I can get rid of my modification to the code Thanks for the infor on parameters. Flemming
