CIFTI Connectivity File Format

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.

The CIFTI-2 specification is in pdf files attached to forum posts, see:
