  optional arguments:
       -h, --help            show this help message and exit
       -r IMAGE, --restored-image IMAGE
                             Restored image file from which to build mask
       -m MASK, --mask-image MASK
                             Input mask file(s). Either --restored-image or --mask-
                             image must be specfied.
       -t THRESHOLD, --threshold THRESHOLD
                             Sigma threshold for masking (default = 6.5)
       -b BOXSIZE, --boxsize BOXSIZE
                             Box size over which to compute stats (default = 50)
       --savenoise           Enable to export noise image as FITS file (default=do
                             not save noise image)
       --merge MASK(s)|REG(s) [MASK(s)|REG(s) ...]
                             Merge in one or more masks or region files
       --subtract MASK(s)|REG(s) [MASK(s)|REG(s) ...]
                             Subract one or more masks or region files
       --number-islands      Number the islands detected (default=do not number
                             islands)
       --remove-islands N|COORD [N|COORD ...]
                             List of islands to remove from input mask. e.g.
                             --remove-islands 1 18 20 20h10m13s,14d15m20s
       --ignore-missing-islands
                             If an island specified by coordinates does not exist,
                             do not throw an error
       --extract-islands N|COORD [N|COORD ...]
                             List of islands to extract from input mask. e.g.
                             --extract-islands 1 18 20 20h10m13s,14d15m20s
       --minimum-size MINSIZE
                             Remove islands that have areas fewer than or equal to
                             the specified number of pixels
       --make-binary         Replace all island numbers with 1
       --invert              Invert the mask
       --dilate R            Apply dilation with a radius of R pixels
       --erode N             Apply N iterations of erosion
       --fill-holes          Fill holes (i.e. entirely closed regions) in mask
       --sum-peak SUM_PEAK   Sum to peak ratio of flux islands to mask in original
                             image.e.g. --sum-peak 100 will mask everything with a
                             ratio above 100
       -o OUTFILE, --outfile OUTFILE
                             Suffix for mask image (default based on input name
       --gui                 Open mask in gui.
