.SH OPTIONS
.SS File-IO
.RS
.IP "\-i \-\-in-file=(required, input); io"
image to be segmented
 For supported file types see PLUGINS:3dimage/io
.IP "\-c \-\-class-file=(required, output); io"
class probability images, the image type must support multiple images and floating point values
 For supported file types see PLUGINS:3dimage/io
.IP "\-b \-\-out-file=(output); io"
Bias corrected image will be of the same type like the input image. If this parameter is not given, then the bias correction will not be applied.
 For supported file types see PLUGINS:3dimage/io
