WebJun 1, 2024 · Backbone of the 3j5p model before (a) and after (b) refinement shown in black. The model before refinement contains a substantial number of steric clashes (indicated by red dots) and many side-chain rotamer outliers (blue side chains). Most clashes and rotamer outliers are resolved by phenix.real_space_refine. WebThe R-free value is then calculated by seeing how well the model predicts the 10% that were not used in refinement. For an ideal model that is not over-interpreting the data, the R-free will be similar to the R-value. Typically, it is a little higher, with a value of about 0.26.

When asked to pick a residue or atom, the cursor changes from the normal arrow shape to a "pick" cursor. Sometimes it is difficult to see the default pick cursor, so you can change it using the function (set-pick-cursor ... WebPhenix will perform bulk-solvent correction and scaling on the data and calculate a likelihood-weighted 2mFo-DFc map. This is compared to a map calculated from the model alone, and correlation coefficients for each residue are obtained. At resolutions better than 2.5 Angstroms, the values for individual atoms will also be displayed.
