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).

Input Image Parameters¶

--phase-encode

Define the phase-encoded image coordinate direction. Supported values: "phase-encode-ap", "phase-encode-is", "phase-encode-lr", where the default is "phase-encode-ap", or use one of the following:

--no-flip

Use this switch is the reverse phase-encoded image does not need to be flipped prior to unwarping. If normal and reverse phase-encoded image display in the same gross orientation in 'triplanar', then flipping is not necessary and must be turned off using this switch.

Optimization Parameters¶

--no-init-shift-com

Disable initialization of unwarping by shifting each row to align the centers of mass of forward and reverse acquisition. Instead, use all-zero initial deformation field.

--smooth-sigma-max <double>

Maximum image smoothing kernel width for coarsest level of multi-scale computation. [Default: 8]

--smooth-sigma-min <double>

Minimum image smoothing kernel width for finest level of multi-scale computation (0 = no smoothing; original image scale). [Default: 0]

--smooth-sigma-diff <double>

Difference between image smoothing kernel widths between two successive levels of the multi-scale computation. [Default: 0.25]

--smoothness-constraint-weight <double>

Weight factor for the second-order smoothness constraint term in the unwarping cost function. [Default: 0]

--folding-constraint-weight <double>

Weight factor for the folding-prevention constraint term in the unwarping cost function. [Default: 0]

--iterations <integer>, -i <integer>

Number of L-BFGS optimization iterations (per multi-scale level). [Default: 10]

Output Options¶

--write-jacobian-fwd <string>

Write Jacobian intensity correction map for forward image. [Default: NONE]

--write-jacobian-rev <string>

Write Jacobian intensity correction map for reverse-encoded image. [Default: NONE]
