[Chimera-users] rebuild DNA

[Elaine Meng]

Dear Damien,
Sorry, Chimera does not have automated methods for building all-atom models from chain traces, either protein or DNA.  Chimera's Build Structure tool (under Tools... Structure Editing) enables manual, step-by-step building, but it is not guided by an input backbone trace, and it would be far too tedious for such long chains anyway.

I haven't done much building in other programs, but I try to keep track of useful web servers.
For protein CA traces, there is a Maxsprout server, but for nucleic acid building, I only know of one web server (make-na) and I believe it just builds the whole thing from scratch and cannot be guided by a chain trace.

<http://structure.usc.edu/make-na/>
<http://www.ebi.ac.uk/Tools/maxsprout/>

Sorry I couldn't help more -- maybe someone else on the list will know of a suitable program.
Elaine
