Dear Brainstorm Team,
- I am using the AAL1 brain atlas to identify my ROIs and get the number below in the connectivity matrix, as far as I understand from the connectivity tutorial this number doesn't reflect my data.
- When I use the function [GetConnectMatrix] I get a 4D matrix the first two dimensions are two sets of signals A and B what do these signals represent?
3)I am using Power spectrum density (Welch) to get the source power for my ROIs and I get 94 ROIs as below but the AAl Atlas as identified in brainstorm has 99 regions
- It was mentioned in a previous question: "To my knowledge, there are still no tools working correctly for connectivity analysis on unconstrained source models (3 dipoles with orthogonal directions for each 3D location). Therefore, I recommend doing your source analysis with constrained locations and constrained orientations."
Help for connectivity pipeline - #3 by Francois
but I am using volume source localization so I cannot use constrained
Kindly, address my inquiries.
Sincerely,
Abrar
