We are pleased to announce the release of DOCK 6.11. DOCK is a suite of programs for molecular docking. The source code for DOCK 6.11 is available for download and free for academic users at http://dock.compbio.ucsf.edu/DOCK_6/index.htm This is a release of the new descriptor-driven de novo design method DOCK_D3N which takes advantage of the integration of the open source toolkit RDKit into DOCK6. DOCK_D3N tailors ligand growth towards desirable regions of chemical space by calculating cheminformatic descriptors at each stage of ligand construction.
