I am trying to group atoms in an orderly fashion using spatial
dimensions. I am finding that if I split my area of interest into
subregions and then group, if there are atoms sitting exactly on the
subregion boundary the atoms will be grouped in both of the groups on
the two sides of the boundary. Is there away to control in a
predetermined way which group an atom would belong to (i.e. group only
if <= a boundary and > another boundary). I see in the code that the
"match" in regions tests for the inclusion in groups, but I can not find
where "match" is actually defined.
Thanks,
Rob
