xform2scalar(1) The Computational Morphometry Toolkit xform2scalar(1)
NAME
xform2scalar - Extract scalar measures from transformations and deformation fields
SYNOPSIS
xform2scalar InputImage XformList
DESCRIPTION
This tool extracts scalar measures from transformations and deformation fields, sampled at grid locations, and writes the results to an
image. Examples of supported scalar measures are: x,y,z component of the transformation, magnitude of the transformation, and Jacobian
determinants.
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.
--xml
Write command line syntax specification in XML markup (for Slicer integration).
--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).
Operating Options
--mode
Mode of operation: type of scalar measure to be extracted. Supported values: "x-component", "y-component", "z-component", "magni-
tude", where the default is "magnitude", or use one of the following:
--x-component
X component of transformation vector.
--y-component
Y component of transformation vector.
--z-component
Z component of transformation vector.
--magnitude
Magnitude of the transformation vector. [This is the default]
--warp-only, -w
Output warp component only (excluding affine).
Output Options
--type
Scalar data type of output image. Supported values: "float", "double", where the default is "double", or use one of the following:
--float
Single-precision float.
--double
Double-precision float. [This is the default]
--output <image-path>, -o <image-path>
Output path for image with extracted scalar data. [Default: NONE]
