1. Unaligned and compressed multi-frame micrographs
Category:
micrographs - multiframe
Image format:
MRCS
No. of images or tilt series:
3383
Image size:
(3838, 3710)
Pixel type:
UNSIGNED 16 BIT INTEGER
Pixel spacing:
(0.5175, 0.5175)
Details:
Data collection was performed using a dose of ~91.56 e-/Å2 across 80 frames (75 msec per frame) at a dose rate of ~4.0 e–/pix/sec, using a set defocus range of -1.2 μm to -1.8 μm. Raw frames were compressed using pbzip2. Gain reference image to use is 18jun08i_08213559_01_3710x3838_norm_0_mod.mrc. Magnification anisotropy is present (Distortion angle of 172.7 degrees, major scale of 1.007 and minor scale of 0.993). The script to correct for magnification anisotropy (mag_distort_correct4.cs is attached, and it requires the mag_distortion_correct software available from the Grigorieff lab website.

2. Aligned and magnification anisotropy corrected micrographs
Category:
micrographs - single frame
Image format:
MRC
No. of images or tilt series:
3297
Image size:
(3838, 3710)
Pixel type:
32 BIT FLOAT
Pixel spacing:
(0.5175, 0.5175)
Details:
Micrographs aligned using MotionCor2, magnification anisotropy corrected. Alignment was done initially using 3x3 patches (Patch3_micrographs). Micrographs that had estimated resolution at 0.5 confidence level of worse than 10 Å were removed, resulting in 3,297 micrographs. Patch2_micrographs were used later during refinement - hence only a subset of micrographs were aligned using 2x2 patches (Patch2_micrographs).
