NAME

       fit_spline_dfield - Deformation Field to Transformation

SYNOPSIS

       fit_spline_dfield InputDField OutputXform

DESCRIPTION

       Fit a parametric nonrigid transformation (B-spline free-form deformation) to a deformation
       field

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.

       --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).

   Input Options
       --absolute
            Input is an absolute transformation field [x maps to input(x)] [This is the default]

       --relative
            Input is relative deformation field, e.g., a gradient  or  force  field  [x  maps  to
            x+input(x)]

   Fitting Options
       --levels <integer>
            Number of levels in the multi-level B-spline approximation procedure.  [Default: 1]

       --fit-affine-first
            Fit affine transformation first, then initialize spline with it.

   Output Options
       --final-cp-spacing <double>
            Final control point grid spacing of the output B-spline transformation.  [Default: 0]

       --final-cp-dims <string>
            Final  control point grid dimensions (i.e., number of controlpoints) of the output B-
            spline transformation. To be provided as 'dimX,dimY,dimZ'.  [Default: NONE]
