Figure 8
Two-dimensional plots illustrating where the maps with similarity scores smaller than 0.2 are distributed in the plane spanned by the first and second PCs, predominantly explaining the variance in 1000 PR maps, regarding the PR calculations for the diffraction patterns from (a) gold colloidal particles [Fig. 1(a

)], (b) a chloroplast of C. merolae [Fig. 7(a

)] and (c) a nucleus of budding yeast [Fig. 7(b

)]. In each plot, the positions of PR maps are indicated by black dots. The red dots indicate the positions of maps with similarity scores smaller than 0.2 projected on the plane. The representative maps of the clusters appearing by the PCA are shown. The cyan background indicates the cluster selected as the most probable maps in the previous studies (Oroguchi et al., 2015

; Sekiguchi et al., 2016

). The scale bar indicates 500 nm.
