       xform2dfield - Transformation to Deformation Field


       xform2dfield OutputPath ReferenceImage XformList


       Convert parametric rigid or nonrigid transformation to deformation field, sampled at pixel
       locations of a given reference image


   Global Toolkit Options (these are shared by all CMTK tools)
            Write list of basic command line options to standard output.

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

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

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

            Write toolkit version to standard output.

            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).

   Main Options
       --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]

            Make  output  deformation  field  with  absolute target location vectors, rather than
            relative offset vectors.
