Subject: [AMBER] Exclamation marks in trajectory

Hello Amber Community,

I recently had a trajectory generated by PMEMD 10 that would only
partially load in VMD. A few hundred frames along it would stop and
print the error, "Problem loading CRD file." Upon closer examination of
the trajectory I found several exclamation points in the file, always
appearing just in front of a number. After I removed them the
trajectory loaded normally into VMD. Does anyone have any idea why
these exclamation points would appear or what they might mean?
