Are these periodic or non-periodic trajectories? If they are non-periodic,
I think you must add the "nobox" keyword for trajout. It's worth a try
if you do have a non-periodic simulation.
Carlos Simmerling's suggestions were good ones. An additional idea is to
learn enough about the format of the trajectory files to edit it with a
text editor, and see what might be wrong.
...good luck...dac
