NAME

       pyFAI-average - image preprocessing tool

DESCRIPTION

       usage: pyFAI-average [options] [options] -o output.edf file1.edf file2.edf ...

       This  tool can be used to average out a set of dark current images using mean or median filter (along the
       image stack). One can also reject outliers be specifying a cutoff (remove  cosmic  rays  /  zingers  from
       dark)

   positional arguments:
       FILE   Files to be processed

   optional arguments:
       -h, --help
              show this help message and exit

       -V, --version
              show program's version number and exit

       -o OUTPUT, --output OUTPUT
              Output/ destination of average image

       -m METHOD, --method METHOD
              Method used for averaging, can be 'mean'(default) or 'min', 'max', 'median', 'sum', 'quantiles'

       -c CUTOFF, --cutoff CUTOFF
              Take the mean of the average +/- cutoff * std_dev.

       -F FORMAT, --format FORMAT
              Output file/image format (by default EDF)

       -d DARK, --dark DARK
              Dark noise to be subtracted

       -f FLAT, --flat FLAT
              Flat field correction

       -v, --verbose
              switch to verbose/debug mode

       -q QUANTILES, --quantiles QUANTILES
              average out between two quantiles -q 0.20-0.90

       It  can  also  be  used  to merge many images from the same sample when using a small beam and reduce the
       spotty-ness of Debye-Sherrer rings. In this case the "max-filter" is usually recommended.
