Supplemental figure 4 I is the same figure (almost) as the cover image for Arroyo et al. I see that middle right of figure 4 becomes top middle of the cover figure, thus a 90 degree counter clock wise rotation with a horizontal flip. The figure is cropped slightly to fit the orientation of the cover but since there is no insert the former shows more molecules. The cover image is slightly squished horizontally compared to Figure 4, but I am going to assume that any manipulations of ratio of height to width would have been done in the cover not the original image (probably not a good assumption). Top figure shows the cover in near-perfect alignment with Supp Fig 4, bottom figure shows cover and Figure 4 I side be side. So measures of the cover images can be subjected to morphometry (as duplicates where they are duplicated, and as additional images where they are not previously measured using the Supp Figure 4 dodecamer bar marker.
