How do I run "Autodock"?

Please note: The FAQ pages at the HPCVL website are continuously being revised. Some pages might pertain to an older configuration of the system. Please let us know if you encounter problems or inaccuracies, and we will correct the entries.

The usage of AutoDock is explained in the User's Manual which is available for download in html, postscript, and pdf formats.

Input files for Autodock are in a PDBQS format for the macromolecule and in a PDBQ format for the ligand molecule. Autodock comes with additional ultilities such asmol2topdqs and addsol to convert other formats (such as mol2). For details, please check the documentation.

Assuming that we have input files ligand.pdbq and macro.pdbqs, we need to make a Grid Parameter file (gpf) and a Docking Parameter file (dpf) which can be created using themkgpf3 and mkdpf3 programs. Both are part of the Autodock distribution:

% mkgpf3 ligand.pdbq macro.pdbqs % mkdpf3 ligand.pdbq macro.pdbqs 

This produces input files for autogrid3 and autodock3, which are called macro.gpf andligand.macro.dpf. Both files might have to be edited manually before being used. The main part of an Autodock run then consists in calls to autogrid3 (for calculating a grid map) and autodock2 (for docking):

% autogrid3 -p macro.gpf -l macro.glg % autodock3 -p
ligand.macro.dpf -l ligand.macro.dlg

The -l option is used to specify log files, whereas the -p defines the input. Various other output files will be produced, someof which can be used to inspect the docking result graphically. Other utilities such as get-docked are supplied to perform the necessary conversions.

The usage of Autodock is quite complex, and the outline here cannot replace the study of the manual. A postscript version of the latter may be found in /opt/autodock/doc.
