[Jmol-users] how to display a difference of spherical caps?

[Victor R. G. <ros...@gm...>]

Hello everybody,

I want to use Jmol to display the atoms within a certain range of distances
from a selected atom. Let's say I want to visualize the atoms within the
range 8.0 to 8.5 angstroms from atom number 860. If I use

display within(8.5, atomno=860)

I see all the atoms from 0 to 8.5 angstroms.  If I use:

hide within (8.0, atomno=860) I see all the atoms at 8.0 and beyond.

So, my question is: how can I define an atom expression that selects all
atoms at least 8.0 angstroms away from atom 860, but not farther away than
8.5 angstroms?

any help appreciated

Victor
