Figure 3
dials.cosym plots for data from lysozyme Sm soaks as described in Section 4.1 ![[link]](../../../../../../logos/arrows/d_arr.gif) . (a) Histogram of (n × m)2 pairwise Rij correlation coefficients and (b) the (n × m) vectors x determined by the minimization of equation (2) during symmetry determination with dials.cosym. The Rij correlation coefficients are clustered towards 1 and the majority of the vectors x form a single cluster, suggesting the absence of an indexing ambiguity, i.e. the Patterson group of the data set corresponds to the maximum lattice symmetry. (c, d) As above but after symmetry determination and scaling. The distribution of the n2 Rij correlation coefficients is sharpened towards 1 as scaling improves the internal consistency of the data. There is also an effect from multiplicity when comparing with (a), as here the n2 Rij values are calculated in the highest symmetry group for the lattice. All but one of the n vectors x form a tight cluster, with the vector lengths close to 1. Visualization of (e) the distribution of unit-cell parameters and (f) clustering on unit-cell parameters suggests the presence of an outlier data set. |
