[Chimera-users] centre of local mass

It seems all would depend on the definition of local. Maybe you can mask or volume-erase or vop zone (around your current marker) to remove or zero the parts that you consider to be nonlocal, then measure center of mass of the resulting map? I don’t know how well that would work, however.
I was also thinking about some kind of filtering or binning (e.g. other vop options), but that might reveal a low-res maximum rather than a center of mass.
I hope this helps,
