Returns the TRACULA (TRActs Constrained by UnderLying Anatomy) white matter bundle atlas in MNI space.
Value
A ggseg_atlas object with components:
- atlas
Character. Atlas name ("tracula")
- type
Character. Atlas type ("tract")
- palette
Named character vector of colours for each tract
- data
A
ggseg_data_tractobject containing:- centerlines
List of centerline matrices per tract
- sf
Simple features data frame for 2D rendering
Details
This atlas contains major white matter tracts reconstructed from diffusion MRI using FreeSurfer's TRACULA training data. It works with both ggseg (2D slice projections) and ggseg3d (3D tube mesh visualizations).
