[gmx-users] trajectory film

[mah maz]

Dear all,
I have a question probably not related to this mailing list! I want to see
a film of an output trajectory via VMD. I tried the .trr file by the
appropriate format in VMD, it shows that the frames are being constructed
and rendering is complete but nothing can be seen. Is there a problem with
my .trr file? Can anyone help me in this regard?
thanks!
