please see my reply to your previous mail.

your .gro file is not conformant to the .gro sprecifications
(or at least according to what whoever wrote the gromacs

(or some arbitrary numbers at the end of the file, and it
will work.

unfortunately, there is no easy way to make the gromacs plugin
more forgiving for this kind of omission, since that would
kill the support for .gro format trajectories in turn.
