Hi. I am trying to fix atoms (or residues) in place during the relax application. After searching through the forum, I saw that MoveMap could be used to accomplish this for the FastRelax application. I assume this is the same thing as the "fast" option for relax in the newest version of Rosetta. The old post I am referring to can be found here http://www.rosettacommons.org/content/frelax-relaxation-constrains. However, I am unsure how the commands listed at the end of the post can be applied. Can they be used within the options file? If so, how would one "set up an instance" of MoveMap within the relax application? Thanks for your help.
