1. Unaligned multi-frame movies
Category:
micrographs - multiframe
Image format:
TIFF
No. of images or tilt series:
6936
Image size:
(11520, 8184)
Pixel type:
UNSIGNED BYTE
Pixel spacing:
(0.415, 0.415)
Details:
Movies were recorded automatically using EPU on a K3 camera in super-resolution mode on a Titan Krios microscope operated at 300 kV (Cs=2.7) equipped with an energy filter using a slit width of 20 eV. The 2.3 second movies contain 59 frames and the super resolution pixel size is 0.415 Å/px. The total dose per movie is ~49.2 e/Å^2. The gain reference image is included.

2. Dose-weighted aligned micrographs
Category:
micrographs - single frame
Image format:
MRC
No. of images or tilt series:
6936
Image size:
(5760, 4092)
Pixel type:
32 BIT FLOAT
Pixel spacing:
(0.829, 0.829)
Details:
Movie frames were corrected for beam-induced motion and dose-weighted using RELION’s motion-correction implementation with following arguments:
--first_frame_sum 1 --last_frame_sum -1 --use_own --j 4 --bin_factor 2 --bfactor 150 --angpix 0.415 --voltage 300 --dose_per_frame 0.81 --preexposure 0 --patch_x 4 --patch_y 4 --gainref Gain.mrc --gain_rot 0 --gain_flip 0 --dose_weighting --save_noDW --only_do_unfinished --early_binning
