GlobalToolkitOptions(thesearesharedbyallCMTKtools)--help
            Write list of basic command line options to standard output.

       --help-all
            Write complete list of basic and advanced command line options to standard output.

       --wiki
            Write list of command line options to standard output in MediaWiki markup.

       --man
            Write man page source in 'nroff' markup to standard output.

       --xml
            Write command line syntax specification in XML markup (for Slicer integration).

       --version
            Write toolkit version to standard output.

       --echo
            Write the current command line to standard output.

       --verbose-level<integer>
            Set verbosity level.

       --verbose, -v
            Increment verbosity level by 1 (deprecated; supported for backward compatibility).

       --threads<integer>
            Set maximum number of parallel threads (for POSIX threads and OpenMP).

   MainOptions--binarize, -b
            Binarize levelset and write as byte mask, rather than write floating-point levelset function itself.

   Theseparameterscontroltheinitializationofthelevelsetfunction--scale-initial-sphere<double>
            Scale factor to reduce or increase the size of the initial foreground region sphere.  [Default:1]Theseparameterscontroltheevolutionofthelevelsetfunction--iterations<integer>, -n<integer>
            Maximum number of iterations [Default:100]--force-iterations, -f
            Force given number of iterations, even when convergence has been detected

       --filter-sigma<double>, -s<double>
            Gaussian filter sigma in world coordinate units (e.g., mm) [Default:2]--delta<double>, -d<double>
            Time constant for levelset evolution; must be > 0; larger is faster [Default:0.1]--levelset-threshold<double>, -t<double>
            Levelset threshold: levelset function is truncated at +/- this value [Default:1]Image/TransformationDatabase--db<string>
            Path  to  image/transformation  database  that  should  be  updated  with  the  newly created image.
            [Default:NONE]
