Dear Amber Community,

I am curious about the imaging done in hybrid remd calculations.

If I use ptraj commands (see below) to post process a trajectory then
the imaged trajectory looks like what one would expect (see attached
However, if I look at the stripped restart file then the imaging seems
to be a bit strange (see the other attached picture). Could anyone
comment on this?

ptraj commands:

trajin coords
center * mass origin
image origin center
solvent byname WAT TIP3
closest 350 :mask first
trajout coords.strip nobox
