.SH NAME
fit_spline_xform \- Fit Single B-Spline Transformation to Concatenated Transformation List
.SH SYNOPSIS
\fBfit_spline_xform\fR InputImage XformList 
.SH DESCRIPTION
Fit a parametric nonrigid transformation (B-spline free-form deformation) to a list of concatenated, optionally inverted, transformations.
.SH OPTIONS
.SS Global Toolkit Options (these are shared by all CMTK tools)
.TP 5
\fB\-\-help\fR
Write list of basic command line options to standard output.
.TP 5
\fB\-\-help-all\fR
Write complete list of basic and advanced command line options to standard output.
.TP 5
\fB\-\-wiki\fR
Write list of command line options to standard output in MediaWiki markup.
.TP 5
\fB\-\-man\fR
Write man page source in 'nroff' markup to standard output.
.TP 5
\fB\-\-version\fR
Write toolkit version to standard output.
.TP 5
\fB\-\-echo\fR
Write the current command line to standard output.
.TP 5
\fB\-\-verbose-level\fR \fI<integer>\fR
Set verbosity level.
.TP 5
\fB\-\-verbose\fR, \fB\-v\fR
Increment verbosity level by 1 (deprecated; supported for backward compatibility).
.TP 5
\fB\-\-threads\fR \fI<integer>\fR
Set maximum number of parallel threads (for POSIX threads and OpenMP).
.SS Fitting Options
.TP 5
\fB\-\-levels\fR \fI<integer>\fR
Number of levels in the multi-level B-spline approximation procedure.
.B [Default: 1]
.TP 5
\fB\-\-fit-affine-first\fR
Fit affine transformation first, then initialize spline with it.
.TP 5
\fB\-\-final-cp-spacing\fR \fI<double>\fR
Final control point grid spacing of the output B-spline transformation.
.B [Default: 0]
.TP 5
\fB\-\-final-cp-dims\fR \fI<string>\fR
Final control point grid dimensions (i.e., number of controlpoints) of the output B-spline transformation. To be provided as 'dimX,dimY,dimZ'.
.B [Default: NONE]
.SS Input Options
.TP 5
\fB\-\-inversion-tolerance\fR \fI<double>\fR
Numerical tolerance of B-spline inversion in mm. Smaller values will lead to more accurate inversion, but may increase failure rate.
.B [Default: 1e-08]
.SS Output Options
.TP 5
\fB\-\-output\fR \fI<transformation-path>\fR, \fB\-o\fR \fI<transformation-path>\fR
Path for the output transformation.
.B [Default: NONE]
