Unit-cell expansion allows reciprocal-space subsampling. (a) The unit cell of the input PDB entry is expanded to create the desired unit-cell sampling, each term in Guinier's equation is calculated separately and then the second term is subtracted from the first to obtain the diffuse intensity. The `pseudo-unit cells' are then averaged across, producing the final diffuse scattering map. (b) Unit-cell expansion allowing for 3× subsampling of reciprocal space. True/`pseudo' Bragg peaks are shown in black/orange and red, respectively. The intensity values of the eight pseudo peaks and one orange peak in the blue box are averaged and the resulting value is assigned to the Bragg index of the orange peak. (c) Pearson correlation coefficients between maps. |
