interfaces.ants.segmentation does not have options for PriorLabelImage arguments

[eilidhmacnicol]

Summary: PriorLabelImage argument for Atroposis accepted as an initialization, but there is no option for PriorLabelImage declaration and prior weighting isn't included in the command. So:
command-line argument currently reads --initialization PriorLabelImage[k]
instead of: --initialization PriorLabelImage[k, priorlabelimage.nii, weighting]

[effigies]

What are the types of the inputs? Looks like the second is a file, and I assume weighting is a float (does it have a limited range?). Is k an integer?

[eilidhmacnicol]

That's it exactly: k is the number of segments to be produced, so an integer, then a discrete segmentation image to use as a prior, and a weighting score for the prior (relative to the input image) between 0 and 1.

It is pretty much the same format as the PriorProbabilityImage option, but it uses a label image to define tissue classes rather than a set of probabilistic images for each tissue class.
