make_initial_affine - Initialize affine transformation

       CMTK  is  developed  with support from the NIAAA under Grant AA021697, National Consortium on Alcohol and
       Neurodevelopment in Adolescence (N-CANDA): Data Integration Component. From April 2009 through  September
       2011, CMTK development and maintenance was supported by the NIBIB under Grant EB008381.

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).

   Transformationconstructioncontrol--mode
            Mode   selection   for  initialization  Supported  values:  "direction-vectors",  "centers-of-mass",
            "principal-axes", "identity", where the default is "direction-vectors", or use one of the following:

            --direction-vectors
                 Alignment based on image direction vectors [Thisisthedefault]--centers-of-mass
                 Alignment based on centers of mass (translation only)

            --principal-axes
                 Alignment based on principal axes

            --identity
                 Create only an identity transformation

       --center-xform, -C
            Set transformation center (for rotation, scale) to center of reference image.

       --native-space
            Write transformation between the native image spaces, rather than in CMTK standard RAS  space.  This
            is the default when running this tool as a Slicer plugin.

   Image/TransformationDatabase--db<string>
            Path  to  image/transformation  database  that  should be updated with the newly transformation from
            reference to floating image.  [Default:NONE]
