For example, = 2.0 and = -1.0 allows one to calculate a 2FO-FC omit-map. WebFig. 1 depicts on logarithmic scale an F(obs) versus F(calc) plot which shows that even very small structure amplitudes, below the 1 e margin, are accounted for and only a very …

WebCheck Fobs/Fcalc. Should be a straight line. If it is flattening out at the top it means it was overexposed. Trying applying extinction to address this. Check the Normal Probability graph. Reflections not nicely on the line can be omitted. Check where they were in the Fobs vs Fcalc, and see if the Fobs vs Fcalc is closer to being a straight line. WebRemark on using amplitudes (Fobs) vs intensities (Iobs) Although phenix.refine will read both data types, intensities or amplitudes, internally it uses amplitudes in nearly all calculations.
