qFit-protein is sampling density from the symmetry mate #352

Open aks-1113 opened 1 year ago

qFit-protein is selecting conformers that are going into the density for the symmetry mate, thus leading to clashes with the symmetry mate structure.

Examples of such behavior are shown below, where orange conformers are the qFit model, green conformers are the original model, and light blue conformers are the original model's symmetry mate. Maps shown are the deposited 2Fo-Fc map at 1 sigma and the Fo-Fc map at 3 sigma.
