('binary' encoding is not supported, stored as-is) Sorry, I should have made my question clearer.
If iwarp is turned on, shouldn't the molecule be imaged back into the box
(even, if that means "breaking" up the molecule and have it come into the
box from different sides?). And based on that is the behavior of the
molecule affected by this or is it still ok?

Best Regards,

Armin

this is fine. you can use the image command in ptraj to
make it easier to view (center on the molecule of interest
and then image). check the ptraj documentation for details.
