▁of ▁Ros etta D ock ▁diver ged ▁into ▁two ▁branches ▁for ▁subsequent ▁C AP RI ▁r ounds ▁as ▁Jeff rey ▁Gray , ▁who ▁laid ▁the ▁ground work ▁for ▁Ros etta D ock ▁while ▁at ▁the ▁University ▁of ▁Washington , ▁continued ▁working ▁on ▁the ▁method ▁in ▁his ▁new ▁position ▁at ▁Joh ns ▁Hop kins ▁University . ▁M embers ▁of ▁the ▁Baker ▁labor atory ▁further ▁developed ▁Ros etta D ock ▁in ▁Gray ' s ▁absence . ▁ ▁The ▁two ▁versions ▁differ ed ▁slightly ▁in ▁side - chain ▁model ing , ▁de co y ▁selection ▁and ▁other ▁areas . ▁Despite ▁these ▁differences , ▁both ▁the ▁Baker ▁and ▁Gray ▁methods ▁performed ▁well ▁in ▁the ▁second ▁C AP RI ▁assess ment , ▁placing ▁fifth ▁and ▁sevent h ▁respectively ▁out ▁of ▁ 3 0 ▁predict or ▁groups . ▁Jeff rey ▁Gray ' s ▁Ros etta D ock ▁server ▁is ▁available ▁as ▁a ▁free ▁dock ing ▁prediction ▁service ▁for ▁non - com mer cial ▁use . ▁ ▁In ▁October ▁ 2 0 0 6 , ▁Ros etta D ock ▁was ▁integrated ▁into ▁Ros etta @ home . ▁ ▁The ▁method ▁used ▁a ▁fast , ▁cru de ▁dock ing ▁model ▁phase ▁using ▁only ▁the ▁protein ▁back bone . ▁ ▁This ▁was ▁followed ▁by ▁a ▁slow ▁full - atom ▁ref in ement ▁phase ▁in ▁which ▁the ▁orientation ▁of ▁the ▁two ▁interact ing ▁prote ins ▁relative ▁to ▁each ▁other , ▁and ▁side - chain ▁interactions ▁at ▁the ▁protein – prote in ▁interface , ▁were ▁simultaneously ▁optimized ▁to ▁find ▁the ▁lowest ▁energy ▁con formation
