I don't know wich version you are using, but try to download the last one. I had the same problem a few month ago and I solved it by choosing a random start, because it seemed that ADT didn't recognize properly the ligand starting coordinates relative to the receptor file; the docking run was correct but there was some sort of offset between the ligand conformations and the receptor. By choosing a random start, If everything works fine, you should be able to properly reproduce your docking and to correctly visualize results. Hope this help Alessandro Contini Alle 15:07, martedl 24 giugno 2003, Robert Flight ha scritto: > Hi, > > I'm trying to use a local search (pseudo-sw) to minimize a docked pose of a > ligand into a receptor.
