Rsym/merge = ΣhklΣi|Ii(hkl) − <I(hkl)>|/ΣhklΣiIi(hkl).
Rmeas = Σhkl[N/(N − 1)]1/2Σi|Ii(hkl) − <I(hkl)>|/ΣhklΣiIi(hkl).
Rpim = Σhkl[1/(N − 1)]1/2Σi|Ii(hkl) − <I(hkl)>|/ΣhklΣiIi(hkl) where Ii(hkl), <I(hkl)>, and N represent the intensity measurement, the mean intensity, and the redundancy for reflection hkl, respectively.
CC∗ = [2CC1/2/(1 + CC1/2)]1/2 where CC1/2 is the correlation between two random halves of the datasets, each containing half of the measured intensities for each unique reflection, and CC∗ is an approximation of the correlation coefficient for a noise-free dataset.
Rwork = Σ|Fobs(hkl) − Fcalc(hkl)|/Σ|Fobs(hkl)|, where Fobs(hkl) and Fcalc(hkl) are the observed and calculated structure factor amplitudes of 95% of the reflections used for refinement. Rfree was calculated from the 5% of total reflections that were omitted from the refinement.
