gPPI ROI Results

I am performing a GLM analysis  using individual ROIs and not all ROIs from the disk. Total there are 8 seeds. 


Can we choose connectivity between that seed 1 with, all other seed  targets ( excluding that first seed from targets) ? Should i perform multiple comparisons correction?


Or connectivity betweeen seed 1 with seed 2; seed 1 with seed 3 needs to be checked until seed 1 with seed 8?


Summaray from methods




Individual connection-> seprate GLM




Connection level hypothesis.




Cluster level inferences




Networks identified using a complete-linkage hierarchical clustering procedure[24] based on ROI-to-ROI anatomical proximity and functional similarity metrics[25].




Results thresholded using a combination of a p < 0.05 connection-level threshold and a familywise corrected p-FDR < 0.05 cluster-level threshold[26].
