Dear All, Suppose there is a 10-residue helix, there are 2 of the 10 Calphas do not position so well so the sidechains of the 2 Calphas do not align with the density. Is any Coot commands which can refine the 2 Calpha positions and the corresponding sidechains? By the way, if I use Wincoot, will you let me know how to use Wincoot by inputing command? Smith
