Hello VMD users,

Under "graphics -> representations", the trajectory tab has a option to
"update selection every frame". From the terminal, I believe this can be
accomplished with with command "mol selupdate 0 0 on".

When i use "animate write $TYPE $FILETYPE sel $SEL" on a selection, the
selection is not updated. I assume the output atoms are those captured when
the selection is set. "mol selupdate 0 0 on" does not seem to impact the
output of "animate write." How can I update my selection for every frame
output by "animate write"?
