Hallo: I am trying to replay some old movie of molecular dynamics trajectories (Amber prmtop/dcd). At that time (a couple of years ago I had Chimera of those times) I get the following error message IOError: Trajectory/Restart header line is greater than 80 characters -- invalid! File "/opt/UCSF/Chimera64-1.7/share/Trajectory/formats/Amber/Amber.py", line 354, in SetupFrame raise IOError, "Trajectory/Restart header line is greater than 80 characters -- invalid! See reply log for Python traceback.
