Hi,
I’m working with the Glasser multi-modal parcellation and I’d like to know if
there is some prevalent notion of distance between any two surface ROIs in the
parcellation? If there is, could you please tell me how I could obtain it or
point me to a source?
Thanks a lot!
Regards,
Karthik

Since ROIs are not points, distance between them becomes a trickier
question. Since areas are connected through white matter rather than gray
matter, that also implies that the easy ways to calculate distance may not
be all that biologically relevant. This would point to using tractography

Tractography's distance bias is in its reported strengths. The distances
reported by tractography should not have a significant bias in the same way -

Would that require them to run a separate probtrackx for each seed area? If
the hits are recorded on the su
lines, the more robust the distance measure).
