David, I've attached a class which runs the lcd0.97 reconstruction with fitting turned OFF. It has a line // Turn off track fitting addReconTrks.setNoFitting(); after creating the AddReconTrks process. To replace the standard version in your analysis do the following ... // import hep.lcd.recon.tracking.*; import hep.lcd.util.driver.*; ... public class LCDDriver extends Driver { public LCDTrackDriver() { add(new TrackReco()); add(new TrackAnalyzer()); } } That is, this modified version of TrackReco is NOT in the hep.lcd.recon.tracking package so comment out the import line. Put TrackReco.java and TrackReco.class in your main jas directory along with your LCDDriver. Please let me know if you have any problems. Mike
