After carefully reading the specifications, it is my impression that there is not a proper intent code to encode surfaces where vertices have associated a vector of probabilities.

In this case, should we use NIFTI_INTENT_NONE? I think it would also be possible to "hack" my way around using NIFTI_INTENT_TIME_SERIES, but it doesn't seem very reasonable.

A further complication is that GCS (Gaussian Classifier atlas Surfaces) files of FreeSurfer also store some sort of local information about "cliques".

Would this use case justify the creation of a new data intent?
