This is the number of cage (cuboctahedron) particles initially picked from the micrographs. For the localized reconstruction method, 12 subparticles (vertices) were extracted per cage particle.
For classification and refinement of cages, a low-pass filtered initial model of cages was used. For classification and alignment of vertices, one vertex was extracted from the symmetrized cage map generated in the previous step.
