EMPIAR-10248 : 971 TIFF files.

(1) For the 971 TIFF files, we execulted MotironCorr and CTFfind using Relion 3.0.
    The file "micrographs_ctf.star" was generated after the CTFfind calculation. 

(2) Among the 971 TIFF files of EMPIAR-10248 with_rlnCtfFigureOfMerit > 0.1,
the 20 TIFF files with the best _rlnCtfMaxResolution have been taken. 

$ sort -n -k 13 micrographs_ctf.star | awk '(NF>10)&&($12>0.1){print $1,$12,$13}' |head -20

(3) Each TIFF file has 50 frames. We took only first 25 frames.

Then number of image frames becomes almost 1/100 ( 20/971 /2 = .01029866).
However, using this reduced dataset, we will get a 3D map with almost 3.0 angstrom resolution.
