eroded_wm_segmentation

petpal.preproc.segmentation_tools.eroded_wm_segmentation(input_segmentation_path: str, out_segmentation_path: str | None, eroded_wm_region_mapping: int = 1) → ants.ANTsImage

Generates eroded white matter region on a segmentation image and merges it into the image, saving result as a new segmentation image.

Requires FreeSurfer segmentation with original label mappings.

Parameters:

• input_segmentation_path (str) – Path to input freesurfer segmentation, such as aparc+aseg or wmparc.

• out_segmentation_path (str) – Path to output segmentation image with replaced values in eroded whited matter region.

• eroded_wm_region_mapping (int) – Segmentation mapping for the eroded white matter region in the output image. Default “1”.

Returns:

seg_img (ants.ANTsImage) –

Input segmentation image with values in eroded white matter

replaced with eroded_wm_region_mapping.
