Hi, Just a small side note. There's nothing intrinsically nonsensical about translating more than a box size. The PBC are translation invariant, so you can do anything and have the system be fine. However, for visualization, translating one box length, and put the stuff back in the box, makes as much sense as doing nothing at all.
