VcPpt is an independently developed extension for Vina, a program for flexible ligand docking under Windows OS
Carry out high-throughput screening of compound libraries with Vina and cluster resulting PDB files of ligands by binding energies and by binding positions. Results processing functions do not require Vina installed. Screening scale is unlimited.

Note that grid parameters are automatically computed at step 1 to cover the entire Protease.pdbqt. Optionally (for advanced users) - to focus fitting on a specific protein pocket - enter the x, y, z manually.
At step 3, any number of ligands (100,000 ? - sure) can be drag-dropped for automatic screening.
"Grid box" is a selection of 3D space around the protein.
Ligands are being moved and docked only within constraints of this 3D box.
Box center = "grid center", box size = "grid size".

Docking or screening with VcPpt can be set up in four mouse moves:
