CCL: To calculate ligand binding site in VINA

 Sent to CCL by: "Manish Kumar  Gupta" [mkgupta5 *]
 I am working of Ligand-Receptor docking using VINA.
 How to define binding site coordinates in VINA.
 Previously, I was using GOLD which uses straightforward approaches like Ligand/
 a central point/residue list to define the binding site.
 Please reply
