[HCP-Users] Distance between surface ROIs in MMP

2017-10-03 Thread Gopalakrishnan, Karthik
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 to fin
