Schema: SegmentationConfig in src/thesis/core/config/validators.py.

Reserved for generic-segmentation steps inside the preprocess and meta pipelines. For the standalone SynthSeg workflow, see synthseg.

Field	Type	Default	Constraints	Description
method	str	"synthseg"	one of synthseg / fast / freesurfer	Segmentation backend.
tissue_types	List[str]	["GM", "WM", "CSF"]	—	Tissue classes to segment.
create_masks	bool	True	—	Whether binary masks are emitted alongside the labelled segmentation.
labels	Dict[str, int] | None	None	—	Optional label_name → integer mapping.

Example

segmentation:
  method: synthseg
  tissue_types: [GM, WM, CSF]
  create_masks: true
