Dear Jianyin,
Thanks for the re. Of course its not the most urgent thing and I can use
the old ptraj for imaging ... At the end its a convenience issue to not
switch between different versions for different tasks. So, I thought its
a good thing to ask about it or let people know about the problem.
The mask "*" is correctly recognized but I get this "empty token?"
warning which made me think that one of the options (either "center" or
"origin") for the image command might not be correctly applied. I would
gladly send you a copy but the trajectory is way too big (> 2GB). I
would need to make chunks first and send one small chunk for testing.
Unfortunately I dont have time now as I am preparing a talk for a
conference next week but if the problem persists and no solution is
found I can send you later on this month a traj chunk.
Cheers
vlad
