Hi,
What are the internal version #s of cpptraj where you have the issue
(use cpptraj --internal-version)?
Can you add 'debug trajin 10' before your 'trajin' command? This will
print out some extra info. Post that info here. E.g.
parm something.psf
debug trajin 10
trajin mydcd.dcd
quit
If it's possible to provide me off-list with the PSF/trajectory file
that would also help.
