WebThe program used to refine atomic models in real space is phenix.real_space_refine. The algorithm uses a simplified refinement target function that speeds up calculations, so … WebThen, refinement is performed using the remaining 90%. The 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.
