SYNOPSIS

fit_spline_xform InputImage XformList

DESCRIPTION

Fit a parametric nonrigid transformation (B-spline free-form deformation) to a list of concatenated, optionally inverted, transformations.

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).

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.

--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]

Input Options

--inversion-tolerance <double>

Numerical tolerance of B-spline inversion in mm. Smaller values will lead to more accurate inversion, but may increase failure rate. [Default: 1e-08]

Output Options

--output <transformation-path>, -o <transformation-path>

Path for the output transformation. [Default: NONE]
