[phenixbb] removing Van der Waals repulsion between two atoms

[Miguel Ortiz-Lombardía]

Dear all,

I've a question regarding phenix.refine.
Is it possible in phenix.refine to remove repulsion between a couple
of atoms to see to what
distance they refine when unrestrained?

I'm thinking in something like what in CNS/XPLOR one would do by setting:

igroup
   	 interaction (selection1) (selection2) weights * 1 vdw 0. elec 0. end
end

I've been searching the web for a solution to this question, but
haven't come up with anything.
Sorry if I missed it!

I would appreciate your help.
Cheers,


Miguel
