Re: [ccp4bb] Build DNA to fit density

Hi Wei, If you have an interpretable density, the efficientest way in my opinion, is to construct manually (only 6bp). You can use coot and the button "add residue". Coot can add nucleotide directly at the extremity of your existing nucleic acid model. Hope to help you. Nicolas Le 18/03/1

[ccp4bb] Build DNA to fit density

2013-03-17 Thread Wei Shi
Hi all, I am refining a structure of protein-DNA complex with coot. The DNA in my search model is shorter than the DNA in the crystal, and now I could see the density for extra DNA(6 base pairs) on either end of the search model DNA. But, I don't know how to build the extra DNA back to fit the dens
