Figure 6. Effect of Observation-to-Parameter Ratio on the Improvement in R[free] from Ensemble Refinement
The decrease in the R[free] value between the initial R[free] value and the R[free] value of the best-performing multiple-conformer model for the 50 experimental structures is plotted as a function of the ratio of the number of reflections used in the refinement to the number of atoms in the original one-conformer structure.
