Hi Minnale,

You could try another version as was suggested... Never hurts to try.
The magic number error occurs if the file is screwed. trjconv will
correctly process the trajectory up to the point where the magic
number error occurs, so you can restart from the last good entry in
the file. Out of luck when the whole trajectory is bad. However, you
didn't say what you did with the .tpr files for the separate runs, and
with the individual trajectory (.xtc) files. If you still have these
you can restart from there.
