[PyMOL] Complement or Inverse Selection in Pymol

[Gert K. <KR...@uk...>]

Dear All,

Apologies for my ignorance.  I need to know which solvent molecules are
in the active site of an enzyme (HIV-PR).  I use "tleap" in Amber to
create a solvent waterbox in and around the enzyme.

I found the following command that seems to find the Water molecules in
the active site:

> sele resn WAT within 5 sele resi 25

(ASP25 is in the active site).

Now I want to remove ALL other water/solvent molecules (those that are
not selected).

Is there a method to achieve a complement or inverse selection (to
hightlight ALL other watermolecules that are not currently selected?)

I am able save the selection, but that is a bit more tedious.

Question:  Is there an easy way in Pymol to achieve a "complement" or
"inverse" selection of waters in a solvent box?
Thanks alot and best wishes
Gert Kruger
