RE: [PyMOL] Coloring surfaces by distance

Peter,

Assuming you have an existing selection

   load my_prot.pdb
   select my_sel, resi 100

You can use the within/of operation...

   color cyan, my_prot within 15 of my_sel
   color red, my_prot within 10 of my_sel

If you needed to exclude the region immediately around the selection, you
could do so with

   color green, (my_prot within 7 of my_sel) and not (my_sel expand 4)

By residue is also an option for coloring complete residues.

   color yellow, byres (my_prot within 7 of my_sel) 

Cheers,
Warren
