DOCK Blaster 2.0 - Automated Optimization of Docking Models using Retrospective Docking

Molecular docking is a widely used technique for leveraging protein structure in ligand discovery, but as a method, it remains difficult to utilize due to limitations that have not been adequately addressed. Despite some progress towards automation, docking still requires expert guidance, hindering its adoption by a broader range of investigators. To make docking more accessible, we have developed a new command-line utility called dockopt, which automates the creation, evaluation, and optimization of docking models prior to their deployment in large-scale prospective screens. dockopt outperforms our previous automated pipeline across all 43 targets in the DUDE-Z benchmark, and the generated models for 86% of targets demonstrate sufficient enrichment to warrant their use in prospective screens, with normalized LogAUC values of at least 15%. dockopt is available as part of the Python package pydock3 included in the UCSF DOCK 3.8 distribution, which is available for free to academic researchers at https://dock.compbio.ucsf.edu, and free for everyone upon registration at https://tldr.docking.org.
