The purpose of this tutorial is to provide members of the Rizzo lab a way to benchmark the AutoDock4 software to compare the Pose Reproduction success rates against the DOCK6 software. (Note: The program version used for this experiment was AutoDock4.2.6 and DOCK6.9

I. Introduction

AutoDock4 is a commonly used docking program which assess the affinity of a ligand, a drug candidate to a target site (Protein, Enzyme, RNA). To evaluate a software's ability to accurately reproduce experimental results, an experiment called Pose Reproduction was developed

Pose Reproduction used an experimental known ligand and protein complex from the PDB database and attempts to dock this ligand back into it's original location. If the lowest energy ligand(most energetically favorable) is within 2.0 RMSDh of the original target site, this is referred to as a docking success. If any of the ligands, but not the lowest energy ligand is within 2.0 RMSDh of the original target site, this is referred to as a scoring failure. If none of the ligands are within 2.0 RMSDh of the original target site this is referred to as a sampling failure.

II.Prepping Directories

First step is prepare a file with a list of systems within it. For this docking experiment this file was called


Second step run the script to prepare a directory for each system in the file. The 1st arguement is the list of systems file made in the previous step. The 2nd Arguement is the new directory that will be made where all the AutoDock4 experiments will be performed

bash ./ ../ AutoDock4_Tutorial

The directory where all the directories will be formed is


Each System will have it's own directory in this file
