Re: [PyMOL] pymol question

[Michael L. <mgl...@gm...>]

I'm sure there's a way to actually draw a circle, but for your particular
use it might be better to use a sphere. If you're comfortable with python
scripting, you can use CGO objects. If not, you might do something like
this:

fetch 1hhp
create thing, resi 24 and name ca # create a new object from some single
atom selection
alter thing, vdw=10.0 # set desired radius
rebuild # necessary if spheres have already been shown
show spheres, thing
alter_state 1, thing, x,y,z = 50,60,10 # set desired x,y,z coords
set sphere_transparency, 0.5, thing # make it transparent
zoom
ray

you can also use something like select + within to select all residues
within a cutoff, but I got the impression you wanted a nice visualization.


Hope that helps,
