Hello,
I calculated a functional connectivity between a seed sphere of interest and the 116 AAL regions as implemented in the DPARSFA toolbox.
In DPARSFA, I defined the AAL Atlas as "first" ROI and my seed sphere as second ROI.
As an outcome (ROICorrelation_FisherZ.mat per subject) I get a 117x117 matrix.
I just wanted to get confirmed, that the last (so the 117th) column (or row) of that matrix contains the correlation coefficient with my seed region and all the other regions of the AAL map, right?

Re: AAL Functional Connectivity Matrix
Yes, you are correct. And the last element should be 1, as the seed region to itself.
Best,
