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¶
- --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", "magnitude", 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]
