It's a bit weird indeed. You might be right that it's due to round-off errors. You can try to copy the original gro file and replace the last line with " 4.00000 4.00000 4.00000" to set the box manually. That should rule out whether it's the box, which I can hardly imagine. The other test is to add a shift, but you'd want to make sure that rounding could get an issue then... Hope it helps, Tsjerk -- Tsjerk A.
