Your new box wouldn't be periodc anymore, so this is not entirely
trivial (although it would be easy to code). Furthermore your protein
may diffuse. What you can do is to
order the trajectory (trjorder) to sort them according to distance to
the protein. Drawback is that you will have different water molecules at
