Calculation of Average Diameter: The average diameter of a capsid was estimated as follows:
Chimera Surface Renderings: These renderings were created by overlaying a 3D grid of varying sizes on the atomic model. The low resolution surface utilized a grid spaced at 8 Angstroms, medium resolution used 5 Angstroms, and high resolution used 3 Angstroms. Atoms were counted in each bin of the grid, and a contour surface calculated based on these values.
