NAME¶
antsAI - part of ANTS registration suite
DESCRIPTION¶
COMMAND:¶
- antsAI
- Program to calculate the optimallinear transform parameters for aligning two images.
OPTIONS:¶
-d, --dimensionality 2/3
- This option forces the image to be treated as a specified-dimensional image. If not specified, we try to infer the dimensionality from the input image.
-m, --metric MI[fixedImage,movingImage,<numberOfBins=32>,<samplingStrategy={None,Regular,Random}>,<samplingPercentage=[0,1]>]
- Mattes[fixedImage,movingImage,<numberOfBins=32>,<samplingStrategy={None,Regular,Random}>,<samplingPercentage=[0,1]>] GC[fixedImage,movingImage,<radius=NA>,<samplingStrategy={None,Regular,Random}>,<samplingPercentage=[0,1]>]
- These image metrics are available: MI: joint histogram and Mattes: mutual information and GC: global correlation.
- -t, --transform Rigid[gradientStep]
- Affine[gradientStep] Similarity[gradientStep]
- Several transform options are available. The gradientStep or learningRate characterizes the gradient descent optimization and is scaled appropriately for each transform using the shift scales estimator.
-p, --align-principal-axes
- Boolean indicating alignment by principal axes. Alternatively, one can align using blobs (see -b option).
- -b, --align-blobs numberOfBlobsToExtract
- [numberOfBlobsToExtract,<numberOfBlobsToMatch=numberOfBlobsToExtract>]
- Boolean indicating alignment by a set of blobs. Alternatively, one can align using blobs (see -p option).
- -s, --search-factor searchFactor
- [searchFactor,<arcFraction=1.0>]
- Incremental search factor (in degrees) which will sample the arc fraction around the principal axis or default axis.
- -c, --convergence numberOfIterations
- [numberOfIterations,<convergenceThreshold=1e-6>,<convergenceWindowSize=10>]
- Number of iterations.
-x, --masks fixedImageMask
- [fixedImageMask,movingImageMask]
- Image masks to limit voxels considered by the metric.
-o, --output outputFileName
- Specify the output transform (output format an ITK .mat file).
-v, --verbose (0)/1
- Verbose output.
-h
- Print the help menu (short version).
--help
- Print the help menu. <VALUES>: 1
