Hi George, Sorry, there is nothing like that. You would have to use some other program for satisfaction of multiple constraints/restraints. With Chimera, it would probably be difficult depending on the number of constraints, but you could measure the various distances and then move one structure relative to the other; the distance values will update automatically. <http://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/mouse.html#activedef> I hope this helps, Elaine ---------- Elaine C.

Hello Do you know if there is a way to set interatomic distances to a certain value in chimera (rather than measuring them)?
Basically what I want to do is rotate/translate a peptide with respect to a protein so that a set of interatomic distances between the two are satisfied Many thanks! George
