                    <details>Semi-automatic particle selection was performed using e2boxer.py to obtain the particle coordinates, followed by particle boxing, linearization, normalization, and apodization of the images using Robem. Defocus and astigmatism values used to perform contrast transfer function (CTF) correction were assessed using Robem for the extracted particles. The icosahedrally averaged reconstruction was initiated using a random model generated with setup_rmc and reached 14 A resolution estimated at a Fourier Shell Correlation (FSC) of 0.5. For the last step of refinement, the final maps were CTF-corrected using a B factor of 200 A2.</details>
