cmtk-xform2dfield (1)

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)

--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).

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]

--output-absolute

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