[Chimera-users] Sampling the density of a map in the vicinity of each atom in a model

Hi,
I have a density map in mrc format and a model in pdb format. I would
like to calculate the average density within a 3D window centered at the
coordinates of each atom in the model and include the result as an
attribute for the atom. Despite some effort searching for the answer, I
cannot find out how to do this easily. I could try and go deep into
Python programming but, before I reinvent the wheel, I'd like to know
whether there already is a simpler way to do this in Chimera.

Thanks!

Mario
