TRACULA White Matter Tract Atlas

Returns the TRACULA (TRActs Constrained by UnderLying Anatomy) white matter bundle atlas in MNI space.

Usage

tracula()

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_tract object 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).
