Sure, that would be helpful. On Mon, Dec 5, 2011 at 12:58 PM, Eric Pettersen <pett@cgl.ucsf.edu> wrote:

If SwissSideChain doesn't cover your needs I can send you the same info I sent the SwissSideChain people so they could get their plugin working.  Your rotamers would need to be in Dunbrack format, and then you would still have to do some work but not too much.

Hi Sabuj, There is no user interface way to do that (you'd have to get into code)... however, your question is quite timely, as there is a new plugin that provides a Rotamers-type interface to hundreds of nonstandard residues.  It also makes a new command "swapnaa" to access these residues via command line.

This SwissSidechain plugin is provided by the Molecular Modelling Group at SIB.  Information and download: <http://ludwig-sun1.unil.ch/~dgfeller/SwissSidechain/chimera.html>

You can browse the SwissSidechain database to see if it includes your residue of interest: <http://ludwig-sun1.unil.ch/~dgfeller/SwissSidechain/table.html>

I hope this helps, Elaine ---------- Elaine C. Meng, Ph.D. UCSF Computer Graphics Lab (Chimera team) and Babbitt Lab Department of Pharmaceutical Chemistry University of California, San Francisco

Hi,

How do I add custom residues so that they're usable with swapaa or the

rotamer tool?

Thanks,

Sabuj
