  breizorro [options] --restored-image restored_image

   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
   --extract-islands N|COORD [N|COORD ...]
                         List of islands to extract from input mask. e.g.
                         --extract-islands 1 18 20 20h10m13s,14d15m20s
   --make-binary         Replace all island numbers with 1
   --invert              Invert the mask
   --dilate R            Apply dilation with a radius of R pixels
   --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.
