                    <details>~14.5M particles were initially selected from 14,375 manually curated micrographs
using cryoSPARC 3.1 live. All subsequent data processing was carried out in
cryoSPARC 3.1.These particles were subjected to 3 rounds of 2D classification. A subset of particles from the final round of 2D classification were used to train the Deep Learning particle picker Topaz (as implemented in cryoSPARC 3.1). The Topaz trained model was used to re-extract particles from the 14,375 micrographs, yielding a new particle set comprising ~7M particles.</details>
