subdivide.triangles

Splits every triangle into 4 by adding the edge midpoints, and projects the new vertices onto the sphere, i.e., the new vertices are scaled to unit length. This is the standard icosphere refinement, and it requires the input to be a sphere centered at the origin.

Provides high-level access to neuroimaging data from standard software packages like 'FreeSurfer' <https://freesurfer.net/> on the level of subjects and groups. Load morphometry data, surfaces and brain parcellations based on atlases. Mask data using labels, load data for specific atlas regions only, and visualize data and statistical results directly in 'R'.
