Dear Tsjerk, Thanks for your suggestion. I tried changing the box values, and it still give a deviation, so I have filed a bug report.

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...
