SYNOPSIS

make_initial_affine ReferenceImage FloatingImage OutputXform

DESCRIPTION

Compute initial affine transformation by aligning centers of mass or principal axes

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).

Transformation construction control

--mode

Mode selection for initialization Supported values: "direction-vectors", "centers-of-mass", "principal-axes", "identity", where the default is "direction-vectors", or use one of the following:

--direction-vectors

Alignment based on image direction vectors [This is the default]

--centers-of-mass

Alignment based on centers of mass (translation only)

--principal-axes

Alignment based on principal axes

--identity

Create only an identity transformation

--center-xform, -C

Set transformation center (for rotation, scale) to center of reference image.

--native-space

Write transformation between the native image spaces, rather than in CMTK standard RAS space. This is the default when running this tool as a Slicer plugin.

Image/Transformation Database

--db <string>

Path to image/transformation database that should be updated with the newly transformation from reference to floating image. [Default: NONE]
