Compressed by PDBj:

Image formats and pixel types shown below are those of the original, non-compressed files.

Movies (FoilHole*.mrc) in this entry were compressed to TIFF by EMPIAR Japan to save space and bandwidth.
The compression is lossless in that all pixel intensities remain exactly the same after decompression.
However, some metadata in the MRC header were lost.
The original files before compression are available from EMPIAR EBI.

Compression was carried out by separating (“un-normalizing”) the gain.
The details of the method are described in
https://relion.readthedocs.io/en/release-3.1/Reference/MovieCompression.html#gain-normalised-movies.

Please apply the gain reference (gain-reference.mrc) during processing.

1. Unaligned, gain-corrected micrographs of mitochondrial complex I from mouse heart
Category:
micrographs - multiframe
Image format:
MRC
No. of images or tilt series:
1235
Image size:
(3838, 3710)
Pixel type:
32 BIT FLOAT
Pixel spacing:
(1.054, 1.054)
Details:
The micrographs are the average of 25 unaligned, gain-corrected frames.The dose rate was 5 electrons Å-2 s-1 with 10 s exposure, giving a total dose of 50 e Å-2. The data were recorded on a Krios using a K2 and energy filter (slit width 20 eV). C2 aperture of 70 μm and Objective aperture of 100 μm and defocus range of -1.5 to -3.1 μm.
