Figure 3
An example of an Fo − Fc map for detecting model error, in this case mispositioned tryptophan and methionine side chains (PDB entry 6lmt/EMDB entry EMD-0919). The resolution is 2.66 Å and the Fo − Fc map is contoured at ±4σ (scaled within the mask). Green and red meshes represent positive and negative maps, respectively. The grey mesh is the weighted and sharpened Fo map. This image was created using PyMOL. |
