You would just remove the parts the parts that used Multalign Viewer to write the sequence alignment. The RMSD that the MatchMaker.match() function returns is a carbon-alpha RMSD, so if you needed a full-backbone RMSD that would be more work. Let me know and I can offer guidance on that. Also, match() returns the overall RMSD of the match. To get the per-residue RMSD you would loop over the atom lists returned by the match() function and for corresponding pairs get the distance (== RMSD for two atoms) with: atom1.xformCoord().distance(atom2.xformCoord()). For output purposes you can get a string representation of an atom’s residue with str(atom.residue).</div><div class=""><span class="gmail-m_-8897730003222345391Apple-tab-span" style="white-space:pre-wrap"> </span>Also, unfortunately the attachment to the message has a “.bin” suffix despite being from a Python file that had a “.py” suffix, so if that’s a problem let me know and I can send you the .py file directly.</div><div class=""><br class=""></div><div class="">—Eric<br class=""><div class="">
