Hello Everyone, When I refined a structure, I found strong difference density Fo-Fc at 3 sigma contour for the for five residues which already have occupancy of 1. The density is continuous and so strong as if I did not put the residues there. Why was that? Can I put greater than 1 occupancy for those residues? Thank you very much for your opinions and suggestions! Best wishes, Sun Tang
