Dear Elaine, Dear Marco Many thanks for your message and suggestion. Marco, I took contact with Xian-Jun Lu who is in charge of 3DNA. I'm waiting for his answer. I will give a feedback here. Elaine, I keep in mind the idea of Maxsprout for protein rebuild from trace. About the DNA, since I have the initial DNA portion, not deformed and complete, I tried to make a morph between the complete DNA and its deformed trace. But only the trace of the original structure morphed. A colleague is going to make something using Yasara. Wait and see. Thanks Damien Le 14/04/2011 09:19, sette@uniroma2.it a écrit :
May be you can try here

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.

Sorry I couldn't help more -- maybe someone else on the list will know of a suitable program. Elaine ----- Elaine C. Meng, Ph.D. UCSF Computer Graphics Lab (Chimera team) and Babbitt Lab Department of Pharmaceutical Chemistry University of California, San Francisco

Dear all, Here is a PDB file of a DNA portion. It contains only the atoms of the backbone chain trace. Is there a way to rebuild the remaining parts (sugar,...)?
