Crystallographic statistics.

aNumbers in parentheses refer to the highest resolution shells.
bRmerge  =  ∑h∑i | Ii(h) - |/∑h∑iIi(h), where Ii(h) is the ith measurement of reflection h and is the weighted mean of all measurements of h.
cRderiv  =  ∑h||FPH | - |FP||/∑h|FP|, where FP and FPH are the native and derivative structure factors, respectively.
dRcullis  =  ∑h|||FPH| - |FP|| - |FH||/∑h||FPH| - |FP|, where FH is the calculated heavy atom structure factor.
ePhasing power is defined as (r.m.s FH/r.m.s lack-of closure).
fR  =  ∑h|Fobs - Fcalc|/∑hFobs, where Fobs and Fcalc are the observed and calculated structure factor amplitudes, respectively. Rcryst and Rfree were calculated using the working and test set, respectively.
gResidues in most favoured, additionally allowed, generously allowed and disallowed regions.
