Hi Ricardo, I don't understand your question. Our rotamer libraries come from the Richardson and Dunbrack labs. You could go to their websites if you want to get their whole libraries. You can follow the links to their sites from the manual page of the Chimera Rotamers tool: <http://www.cgl.ucsf.edu/chimera/docs/ContributedSoftware/rotamers/framerot.h...> There is a Chimera command "swapaa" to mutate a residue in a PDB file to another residue, and it uses the rotamer libraries, but I can't tell if that is what you wanted. It does not show a graphical interface with the rotamers. Only the Rotamers tool does that, for the specific amino acid type you choose. <http://www.cgl.ucsf.edu/chimera/docs/UsersGuide/midas/swapaa.html> Elaine ---------- Elaine C.
