[Dock-fans] How to parameterize halide ion ligand

[Francesco Pietra]

Hi:
I am now ready to attempt docking of small molecules onto a large
protein. Ready, except for what concerns halide ion ligands present in
the protein.

The model (from Modeller) saved the spatial relationship of the
made-punctiform halide ion. With DOCK, in procedure all movable, such
restriction would be overridden.Any suggestion how to let DOCK know
about the vdw radious of the halide ion?
Thanks
