Dear Alfonso and conn users,

Using a ROI-to-ROI approach, is it meaningful to calculate an overall network connectivity score based on the individual ROI-to-ROI fiher-z scores? 

To be more specific: 
I have a network of 7 ROIs (defined by me). For each subject I have 21 fisher-z transformed correlation scores representing all possible connections within the network. If I calculate the average of these 21 scores per subject, can it be a meaningful marker of overall network connectivity? 

Thank you in advance,
Réka
