Returns the centerline of each tract, joined with core region info and palette colours. Tract atlases represent each pathway as a curve through the bundle rather than as a surface, and render it by sweeping a tube along that curve, so the centerline — not a mesh — is the geometry that defines them.
Value
data.frame with one row per tract, a points list-column of
n x 3 coordinate matrices and a matching tangents list-column
