Movies in this entry (data/gpc/Frames/*.mrc) 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 compressio0n are available from EMPIAR EBI.

PDBj discovered that `data/Leginon/rawdata` and `data/gpc/Leginon` contained exactly same files.
`data/Frames` and `data/gpc/Frames` are also the same. Therefore, `data/gpc` was removed.
