FIG. 3.
Comparison of AuraT, AuraB, SINV, and RRV reconstructions. Surface-shaded representations of the exteriors (top row), spikes (second row) (threefold [i3] and quasi-threefold [q3] axes), and equatorial cross sections (third row) from AuraT and AuraB, SINV, and RRV allow similarities and differences between these reconstruction maps to be compared. Reconstruction maps of AuraT, AuraB, and SINV are remarkably similar, whereas the RRV spike differs both on its exterior and its interior, where a cavity is present (see arrows on RRV cross section). The two panels on the bottom left are the central sections of the AuraT−AuraB and AuraT−SINV difference maps. The bottom right panel plots the correlation coefficients between different pairs of reconstructions (AuraT−AuraB, AuraT−SINV, and AuraT−RRV) as a function of radius. The color bar at the top of the panel coincides with the color scheme used in the equatorial cross sections (third row): viral genome (pink), nucleocapsid core (orange), lipid membrane (green), and envelope glycoproteins (blue).
