History and Changes

DOCK 3.5 Changes

here is the DOCK 3.5 manual from 1994: [1]

Compilation

DOCK Tools

Docking tools


Flexibase Format

Programs, Files, and Protocols

To run DOCK 3.6 for small molcule docking and virtual screening, you need the following:

  • Receptor grid (generated with delphi)
  • Spheres (coloured with )
  • database file containing conformational expantion of your small molecules.

DOCK 3 INPUT FILE and Parameters

INDOCK for DOCK 3.6
