I've since found the source of my problem - the program was measuring
the (marginally shorter) distance across the PBC boundary, rather than
the distance
within the box. Unfortunately there doesn't seem to be a way to turn
PBC images off (correct me if I'm wrong?), so I guess I'm going to do
some jiggerypokery with the data and some math.
Distance larger than half a box size are ill-defined anyway in a PBC
simulation. In some special cases you can do this, for instance within a
protein it would work. I've implemented -nopbc options in some programs
but not in g_dist yet. Please put it on the developer wishlist. on the wiki.
