As a viz/geometry GEEK, I got very distracted by grayordinates. This animation is an attempt to develop a spatial understanding. This is from the Tutorial dataset, selecting grayordinate 18, 1018, 2018 ... 31018, 32018 on the right cortex and display them on the flat view. The screen shot below conveys more info. The cortex grayordinates are the vertices of a series of triangle strips.

Coalson, Bruce Fischl, Jesper L. Andersson, Junqian Xu, Saad Jbabdi, Matthew Webster, Jonathan R. Polimeni, David C. Van Essen, Mark Jenkinson.

HCP Workbench Connectome Workbench is an open-source visualization and discovery tool used to explore data generated by the Human Connectome Project. The distribution includes wb_view, a GUI-based visualization platform, and wb_command, a command-line program for performing a variety of algorithmic tasks using volume, surface, and grayordinate data.

CIFTI CIFTI (Connectivity Informatics Technology Initiative) standardizes file formats for the storage of connectivity data. These formats are developed by the Human Connectome Project and other interested parties.
