I think the current version of gromacs has a bug in it. Download the CVS
I believe it has been fixed.

Subject: [gmx-users] periodic boundary conditions
I use periodic boundary conditions in my simulations by Gromacs. It said
in the manual that only one - the nearest image of each particle is
considered for short-range non-bonded interaction terms during the
simulations (called minimum image convention).
However, when i try to analysize the trajectory and calculate the
distance between two planes by g_sgangle, I found that the results
aren't got from the nearest image but the images in one cell. So the
results cannot be used directly whenever particles are near the
My question is: When we calculate the total energy by g_energy, is the
result got from images in one cell? If so, are there any method to get
the total energy and the distance from the nearest images?
Thanks in advance!
