The purpose of this tutorial is to develop a uniform method to test pose reproduction across the Rizzo lab with the DOCK software. Note any data in this tutorial is solely for the purpose of example.

I.Introduction

-Pose reproduction is an experiment which tests a docking programs ability to predict the bound pose of a ligand to a receptor (typically a protein). An experimental structure of a protein-ligand complex is converted into 2 separate files, 1 for ligand and 1 for receptor. The docking program then predicts the binding orientation that is most energetically favorable. In the case of DOCK6, the ligand is flexibly docked with the Anchor & Grow algorithm to a rigid receptor.

-The RMSD between the docked poses and experimental pose are measured. We consider RMSD < 2 angstroms an accurate prediction. There are 3 outcomes we classify.

1) Success - The best scoring pose is < 2 angstroms

2) Scoring Fail - A pose < 2 angstroms was sampled but did not score best

3) Sampling Fail - No pose < 2 angstroms was sampled

II.Necessary files

This tutorial uses Single Grid Energy as the primary score for docking. This is the typical score used by the Rizzo Lab for this purpose and for generating poses in Virtual Screening. Thus, grid files are required. The receptor mol2 is only necessary for visualization purposes. The list of necessary files are:
