Servalcat
github.com/keitaroyam/servalcatServalcat is a tool for structure refinement and validation for crystallography and single particle analysis. It is used for Cryo-EM single particle structure refinement and map calculation using Servalcat. Servalcat makes refinement by REFMAC5 easy for single particle analysis. The weighted and sharpened Fo-Fc map is calculated after the refinement.
