Dear Officail, This is Jyo writing from UNT biological sciences at Denton, TX, USA. I have been using your software for my research project for about an year. I was looking for a help/instructions about how to find out the configuration change in the protein after docking with a ligand. I have heard about RMSD docking value, that will be given in Amstrong units, could you kindly instruct me the process to perform it. It would be more glad if you are able to answer me withing a week from now : ) Sincerely, Jyotheeswaran Panapakam, PhD Candidate &Teaching Assistant, Department of Biological Sciences, University of North Texas.
