Anyway, I see a note about this removal here ( http://redmine.gromacs.org/issues/1346 ), though no reason is given. I'd suggest that you revert to a more functional version of gromacs ;)

I think the behavior can be recovered with "direction" geometry, but that
requires each half of the symmetric sampling windows to be set up separately, I
think, rather than just a continuous vector like "position" used to provide.
That's a shame if true. It's a workaround, but it's much less convenient.
