I'm not entirely sure what you want to count, and in which region, but you
could try some of the following:

- ask David Bostick for g_occupancy.c (or perhaps he had already posted
   the code here or on the contributions page?)

- trjorder

- try to compile my g_count
http://sansom.biop.ox.ac.uk/oliver/download/Gromacs/g_count-0.1.tar.bz2
(less general than g_occupancy)

- try to compile my gridcounter (for 3D densities, see
http://sansom.biop.ox.ac.uk/oliver/software/#gridcount )

(Please take note of the remarks in
http://sansom.biop.ox.ac.uk/oliver/download/Gromacs/ with respect to
disclaimers, licensing, compiling and reporting bugs)
