ᴅʀ. ᴍᴏᴡɪɴᴄᴋᴇʟ'ꜱggseg.extra now builds cortical brain atlases directly from the mesh geometry! A 150-region Destrieux atlas tok 9 seconds. No screenshots, no ImageMagick, no headless browser.
Same Destrieux atlas: 53,000 vertices before, 6,000 after. The borders are smoother with fewer vertices because the geometry is right from the start.

ggseg.extra is part of the #ggsegverse ecosystem for brain visualization in R. Dev version on GitHub.
Create Brain Atlases for the ggsegverse Plotting Ecosystem
Create brain atlas data sets compatible with the ggsegverse plotting packages in R. Provides pipelines for building cortical, subcortical, and white-matter tract atlases from FreeSurfer annotation files, GIFTI and CIFTI surface formats, neuromaps, and volumetric NIfTI images.
