Did you set the weight (X-ray.vs.Geom.) too high? In principle, at 3A a relatively smaller weight than default (0.3?) may be used.

Hi Everybody,

I am refining structure of a protein at 3 Angstrom. I am doing model building in
Coot.
After several rounds of refinement using Refmac when I tried to run PROCHECK on my partially build model I found that some of the residues are D- amino acids.

How to change these D-amino acids to L-amino acids??

Is there any option in Coot for that??


Thanks in advance,
yusuf
