AutoDock is a suite of automated docking tools. It is designed to predict how small molecules, such as substrates or drug candidates, bind to a receptor of known 3D structure.

AutoDock Vina does not require choosing atom types and pre-calculating grid maps for them. Instead, it calculates the grids internally, for the atom types that are needed, and it does this virtually instantly.

• Autodock website at Scripps

• Module Name: Autodock or AutodockVina (see the modules page for more information)
• AutodockVina is multithreaded. Autodock is single-threaded.
• The mgltools package that is used to create input files for Vina is also installed. When you load the Autodock or AutodockVina modules, you will also get access to the mgltools executables.
• If you wish to run the mgltools Python scripts you may need to use the pythonsh command available when you load the module. This will ensure your environment is properly set up.
• mgltools is a graphics-intensive package, and can easily be installed/run on your desktop system for better performance. It can be downloaded here.
• The entire PDB (updated once a week) database is available in /pdb on all nodes, the Biowulf login node, and Helix.

Create a batch input file (e.g. autodock.sh). For example:

#!/bin/bash
module load Autodock
autodock4 -p myfile.dpf -l myfile.dlg 

Submit this job using the Slurm sbatch command.

sbatch [--mem=#] autodock.sh

The --mem=#g flag should be used if the autodock run requires more than the default 4 GB of memory.

Create a swarmfile (e.g. myfile.swarm). For example:

cd /data/$USER/mydir;  autodock4 -p lig1.macro.def -l lig1.log
cd /data/$USER/mydir;  autodock4 -p lig2.macro.def -l lig2.log
cd /data/$USER/mydir;  autodock4 -p lig3.macro.def -l lig3.log
cd /data/$USER/mydir;  autodock4 -p lig4.macro.def -l lig4.log
[...]

Submit this job using the swarm command.

swarm -f myfile.swarm [-g #] --module Autodock

where

-g #	Number of Gigabytes of memory required for each process (1 line in the swarm command file)
-t #	Number of threads/CPUs required for each process (1 line in the swarm command file). (not useful for Autodock which is single-threaded, but can be used for a swarm of Vina jobs)
--module Autodock	Loads the Autodock module for each subjob in the swarm

Autodock-GPU processes ligand-receptor poses in parallel over multiple compute units on GPUs. [Autodock-GPU website]
