Rmerge = [ΣhklΣi|Ii(hkl) − 〈I(hkl)〉|]/ΣhklΣi〈Ii(hkl)〉, where Ii(hkl) is the intensity of the ith measurement of reflection (hkl) and 〈I(hkl)〉 is its mean intensity.
I is the integrated intensity, and σ(I) is its estimated standard deviation.
Rwork = (Σhkl|Fo − Fc|)/ΣhklFo, where Fo and Fc are the observed and calculated structure factors, respectively.
Rfree is calculated as described for Rwork but from a randomly selected subset of the data (5%), which were excluded from the refinement calculation.
Calculated by MOLPROBITY.
