Movies (Export/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 (Export/gain-reference.mrc) during processing.

PDBj discovered that this entry contained an ascp binary (`Export/ascp`) and removed it.
PDBj also discovered that three movies in `Export/pentamidine` were duplicates of the
same files in `Export` and removed them.
