Particles were automatically picked from the surface of the vesicles in CTF-corrected cryo-electron tomograms. After a rough alignment deep classification into 20 classes was performed including 4 neighbouring pentamers in the alignment mask. Finally the central pentamers from each class were cropped, aligned and averaged resulting in a final structure.
