[PyMOL] Setting sphere_transparency for individual selections

[Andrew W. <sen...@gm...>]

I've been trying to set the sphere_transparency for selections on my
protein, and I've tried the following:

PyMOL> load test.pdb
PyMOL> show spheres, HETATM

I've tried the following to change sphere_transparencies:
PyMOL> set sphere_transparency,0.4,name COO
PyMOL > cmd.set("sphere_transparency", 0.4, selection=3D"name COO")

neither of these work, as the sphere_transparency gets applied to ALL spher=
es

I know my selection is fine, because I can change the color of this
individual atom by typing:

PyMOL: color red, name COO

Is it possible to change the sphere_transparency setting for individual ato=
ms?
