The defocus range between −0.8 to −2.2 μm and to record two shots for each of the four holes per stage movement through image shift. All movies were exposed with a total dose of 52.0 e-/Å2 for 2.0 s fractionated over 50 frames.
An ideal tilt angle of 37° was calculated from this processed dataset using cryoEF. The defocus range between −1.5 to −3.0 μm with two shots recorded for each hole per stage movement through image shift. All movies were exposed with a total dose of 65.0 e-/Å2 for 2.4 s fractionated over 43 frames
