VMD claims it can handle both Amber6 and 7 prmtop files, though i can't
verify this claim. What version of VMD do you have. Older versions
required babel to be installed though with more recent versions this is
no longer true (I think it just comes with VMD now).

Have you tried opening them with, for example, moil-view, just to make
sure the prmtop/coordinate file pair works? Just to rule out corrupt

Dear AMBER users,

I would like to view trajectories from AMBER7 runs with vmd
1.7. It seems to me that VMD cannot open AMBER7 prmtop

is there a program/script that translates my prmtop file
into the old type of prmtop file (AMBER6 I guess)?

I am aware that xleap can write the old prmtop files with
"oldprmtopformat=on", but I thought maybe it is possible
without creating my system again with xleap.

Best regards,
