Periodic Boundary Conditions? You mention in another post that removing the header solves your 'bug'. The way you express yourself indicates you haven't got a clue what you've removed. Dangerous... Bad idea. You've probably removed a line which started with CRYST1, preceded by a line REMARK This is a simulation box, or something along those lines. Sure, if you remove PBC that way, no gromacs utility will ever see that things should be close to each other. But you're the one that's mistaken, not the program. Don't let yourself be mislead by visualization programs. Hope it helps, Tsjerk -- Tsjerk A.
