Molecular docking is widely used to leverage protein structure for ligand discovery, but the technique retains important liabilities that make it challenging to deploy on a large scale. Notwithstanding multiple attempts at automation, molecular docking continues to require the guidance of an expert thus limiting its use by many investigators who could benefit from it. To make docking more accessible we have created new software that allows us to investigate the automation of molecular docking screens. Our method currently requires known ligands and decoys for model evaluation. Of 42 DUDEZ targets, all show automated docking results that are better than our previous automated protocol. The new system is available both as part of the UCSF DOCK 3.8 package, which is free to academics, as well as via our website (free registration required), which is free to everyone.
