Welcome to the ZDOCK Conv3D homepage. This is a project to integrate the 3D convolution library, Conv3D (provided by Dr. Yuichiro Hourai of the Computational Biology Research Center, AIST, Japan), into the ZDOCK protein-protein docking program (developed by our laboratory). We subsequently made several changes to the ZDOCK algorithm to dynamically adjust the positioning and orientation of input proteins to more efficiently utilize grid space, resulting in further improvements in running time and memory usage. We have integrated these improvements into two versions of ZDOCK: ZDOCK 2.3 and ZDOCK 3.0. These optimized versions of ZDOCK are named ZDOCK 2.3.2 and ZDOCK 3.0.2, respectively.
