ggsegBrainnetome 2.0.6

• The subcortical atlas now renders on a grey-brain anatomical context. The MNI152 parcels are registered into the fsaverage5 aseg and the surrounding cortex, white matter, cerebellum and brainstem are drawn as grey context, so the coloured parcels sit inside a recognisable brain silhouette — matching the FreeSurfer subcortical atlases. Regenerating requires FreeSurfer 7.4.1.

ggsegBrainnetome 2.0.5

• Rebuilt the subcortical atlas 2D geometry with per-atlas projection tuning: bounding-box-derived slabs (3 coronal + 4 axial) and structure dilation, so the 36 fine subcortical parcels render as coherent filled shapes instead of scattered slivers. 3D meshes are unchanged.

ggsegBrainnetome 2.0.4

• Atlas 2D geometry migrated to the sf-optional brain_polygons format (ggseg.formats 0.0.3). The atlases now render without sf and its GDAL/GEOS/PROJ system libraries, enabling wasm and air-gapped installs. Plots are unchanged.

ggsegBrainnetome 2.0.0

Breaking changes

• brainnetome is now a ggseg_atlas object (from ggseg.formats) containing 2D polygon geometry.

• Atlas recreated from scratch using ggsegExtra::create_cortical_atlas() from the BN_Atlas annotation on fsaverage5.

• Use ggplot() + ggseg::geom_brain(atlas = brainnetome) for 2D plots.

• ggseg.formats is now a hard dependency (in Depends).

• Package URLs updated from LCBC-UiO to ggseg GitHub organisation.
