 Development of RosettaDock diverged into two branches for subsequent CAPRI rounds as Jeffrey Gray , who laid the groundwork for RosettaDock while at the University of Washington , continued working on the method in his new position at Johns Hopkins University . Members of the Baker laboratory further developed RosettaDock in Gray 's absence . The two versions differed slightly in side @-@ chain modeling , decoy selection and other areas . Despite these differences , both the Baker and Gray methods performed well in the second CAPRI assessment , placing fifth and seventh respectively out of 30 predictor groups . Jeffrey Gray 's RosettaDock server is available as a free docking prediction service for non @-@ commercial use .
