There's no outside to a periodic cell - you will find a matching cavity
on the other side of the triclinic periodic cell, where some of the
solute atoms actually are also....
GROMACS uses the triclinic representation internally for efficiency - a
2D analogy is that a hexagon tiling a plane can be converted to a
rhombus tiling the plane. It doesn't bother wasting your valuable
computing cluster time converting back to the initial representation,
which probably wasn't wanted. That is, mdrun makes no attempt to guess
how you would like your output to appear. See
for ideas about how to make your output look as you would like.
