Hello Kyle, Which version of the reconstruction are you analyzing?

I get the GBL tracks as normal: List<Track> tracks = null; if(event.hasCollection(Track.class, "GBLTracks")) { tracks = event.get(Track.class, "GBLTracks"); } else { tracks = new ArrayList<Track>(0); } I then attempt to get a track state: for(Track track : tracks) { double[] p = track.getTrackStates().get(TrackState.AtCalorimeter).getMomentum(); System.out.printf("p = <%5.3f, %5.3f, %5.3f%n", p[0], p[1], p[2]); } However, I get this error: java.lang.IndexOutOfBoundsException: Index 4 out-of-bounds for length 3 It seems that the track does not have the track state for the calorimeter stored. Am I doing something wrong?
