User Manuals



Getting Started Guide [HTML]

This introductory guide is aimed at new users of rDock. It describes the minimal set of steps required to build rDock from the source code distribution, and to run one of the automated validation experiments provided in the test suite distribution.
If you only wish to use the pre-compiled version rather than building it from the source code, see tutorial 1 for a briefer setup guide.
The instructions assume that you are comfortable with simple Linux command line administration tasks, and with building Linux applications from 'make' files. Once you are familiar with these steps you should proceed to the User and Reference Guide for more detailed documentation on the usage of rDock.

Reference Guide [HTML]

This document aims to build upon the tasks covered in the Getting Started guide and be a full reference guide for the rDock platform. Whilst still in its development state at present it will eventually cover the software tools, parameter files, scoring functions and search engines. Whilst this document is being expanded the user is encouraged to cross-reference the descriptions with the corresponding source code files to discover the finer implementation details.


Science & Theory


Here you can find a brief explanation of some of the theory behind rDock.


There are three uses of this type of program:

1. Docking: Predicting the binding mode for a compound that is known to bind to a protein active site. For this, a series of different test sets of data have been assembled by the community - the Astex CCDC set is one; the rDock test set another (this includes RNA complexes). The success of docking programs is then assessed as the percentage of test complexes for which the docking program can reproduce within 2A RMSD, the crystallographically observed binding mode.

2. Virtual screening: Using docking calculations to screen a large database of compounds for those that may bind to the active site. The ability of docking programs to do this is measured by something called enrichment factors. Typically, a random set of "drug-like" molecules is assembled, spiked with compounds that are known to bind. The docking program is then used to produce a rank-ordered list of the compounds, predicting which is the most likely to bind. The enrichment factor is then calculated as the ratio of the number of known compounds found in the top (say) 5% of ranked compounds compared to that expected by random. This is often also plotted as an enrichment plot.

3. Ranking binding affinity: Most docking programs include a mechanisms for scoring how well a compound binds to an active site. This is often constructed from an empirical analysis of the binding and affinities of a set of known protein-ligand complexes. In general, it is found that the "fast" scoring functions implemented in most docking programs are unable to predict successfully the relative binding affinity of a set of compounds.

The specific algorithms used by rDock can be found here.
