xform2dfield - Transformation to Deformation Field

       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.

       --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--mask, -m
            Use reference image pixels as a binary mask.

       --target-image-fsl<string>
            Path to optional target image to be used in FSL. This is the image that the transformation (and thus
            the  created  deformation  field)  maps  to. When creating a deformation field to be used with FSL's
            "applywarp" tool, is may be necessary to  determine  whether  the  x  coordinate  of  the  resulting
            deformation vectors has to be flipped.  [Default:disabled]--inversion-tolerance-factor<double>
            Factor  for  numerical  tolerance  of  B-spline  inversion  [multiples  of  minimum grid pixel size;
            default=0.1] [Default:0.1]--downsample<string>
            Downsample grid by factors 'x,y,z' or by single factor 'xyz' [Default:NONE]--output-absolute
            Make output deformation field with absolute target location vectors,  rather  than  relative  offset
            vectors.
