Hippocampus segmentation of the BigBrain

Surfaces are provided for CA1, CA2, CA3, CA4, dendate gyrus, subiculum,
and the mid-surface.

Files:

JSON/*: a complete model in json format (try it with brainbrowser
        https://brainbrowser.cbrain.mcgill.ca/surface-viewer#ct)

A3D/*: these are the surface files to use with Atelier3D (you also need
       to download the full A3D model for the BigBrain volume and place
       these files in the same base directory for A3D)

MNI-obj/*: surfaces in MNI-OBJ format

wavefront-obj/*: surfaces in WaveFront-OBJ format

stl/*: surfaces in STL format

gii/*: surfaces in GIfTI format
