Hello:

In the recent past, issues in running movie with parm7 files were solved. Now, with ambertools14 problems come out again, unless I dropped into a silly mistake.

That is, parm7/dcd was refused because no top file was found. Renaming the prm7 extension prmtop led to

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!!"

Thanks for your kind attention
