You can calculate the distances in ptraj too to confirm and/or make sure
that the distances are less than 3.5 angstroms when you visualize. Also,
turn off the angle (angle -1.0); normally I use angle 120.0 which is +/-
60 deg... angle 180 may be assuming it is exactly linear which would be
rare indeed. --tec3
