Title: FreeSurfer Brain Atlases for the 'ggseg' Ecosystem
Description: FreeSurfer cortical and subcortical brain atlases for the 'ggseg' ecosystem. Includes the Desikan-Killiany-Tourville cortical atlas (Klein & Tourville 2012), the Destrieux cortical atlas (Destrieux et al. 2010), and the HCP subcortical atlas with anterior/posterior hippocampus subdivisions. Provides unified 'ggseg_atlas' objects with 2D polygon geometry and 3D mesh or vertex data, for use with 'ggseg' and 'ggseg3d'.
