       Compute  the  approximate symmetry plane of an image to determine, for example, the mid-sagittal plane in
       human brain images. Various forms of output are  supported,  e.g.,  writing  the  input  image  with  the
       symmetry plane drawn into it, or the input image realigned along the symmetry plane.

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).

   Optimization--accuracy<double>, -a<double>
            Accuracy (final optimization step size in [mm].  [Default:0.1]--sampling<double>, -s<double>
            Resampled  image resolution. This is the resolution [in mm] of the first (finest) resampled image in
            the multi-scale pyramid, which  is  derived  directly  from  the  original  full-resolution  images.
            [Default:1]--levels<integer>, -l<integer>
            Number of resolution levels. The algorithm will create (levels-1) resampled images with increasingly
            coarse  resolution  and  use  these  in  successive  order of increasing resolution before using the
            original images at the final level.  [Default:4]Initialapproximatesymmetryplaneorientation--initial-plane
            Initial orientation of symmetry plane. This should be the closest orthogonal plane to  the  expected
            actual  symmetry  plane.   Supported values: "initial-axial", "initial-coronal", "initial-sagittal",
            "initial-xy", "initial-xz", "initial-yz", where the default is "initial-sagittal", or use one of the
            following:

            Read symmetry parameters from file, skip search.  [Default:disabled]Datapre-processing--min-value<float>
            Force minumum data value.  [Default:disabled]--max-value<float>

            Interpolation method used for reformatted output data Supported values: "linear",  "cubic",  "sinc",
            where the default is "linear", or use one of the following:
