NAME

       sympl - Symmetry plane computation

SYNOPSIS

       sympl InputImage

DESCRIPTION

       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.

OPTIONS

   Global Toolkit Options (these are shared by all CMTK tools)
       --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]

   Initial approximate symmetry plane orientation
       --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:

            --initial-axial
                 Approximately axial symmetry

            --initial-coronal
                 Approximately coronal symmetry

            --initial-sagittal
                 Approximately sagittal symmetry [This is the default]

            --initial-xy
                 Approximately XY plane symmetry

            --initial-xz
                 Approximately XZ plane symmetry

            --initial-yz
                 Approximately YZ plane symmetry [This is the default]

   Pre-computed symmetry
       --output-only <string>
            Give symmetry parameters [Rho Theta Phi] as option, skip search.  [Default: disabled]

       --output-only-file <string>
            Read symmetry parameters from file, skip search.  [Default: disabled]

   Data pre-processing
       --min-value <float>
            Force minumum data value.  [Default: disabled]

       --max-value <float>
            Force maximum data value.  [Default: disabled]

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

            --linear, -L
                 Use linear image interpolation for output.  [This is the default]

            --cubic, -C
                 Use cubic image interpolation for output.

            --sinc, -S
                 Use cosine-windowed sinc image interpolation for output.

       --pad-out <double>, -P <double>
            Padding value for output images.  [Default: disabled]

       --mark-value <double>
            Data value to mark (draw) symmetry plane.  [Default: 4095]

       --write-marked <image-path>
            File name for output image with marked symmetry plane.  [Default: NONE]

       --write-aligned <image-path>
            File name for symmetry plane-aligned output image.  [Default: NONE]
