Fig. 8. Robustness of group difference in community structure to methodological variation.
A) The original methods: functional connectivity is defined as the absolute wavelet correlation at scale 2 (0.05–0.11 Hz), and anatomical regions were defined in order to maximize compactness while allowing some variation in volume (2128 mm3–4256 mm3). B) Only positive correlations included in the networks. C) Scale 3 frequency band (0.03–0.05 Hz). D) Regions constrained to be exactly the same size (1600 mm3). Permutation tests were conducted on sparse, 2% thresholded networks using 10,000 random permutations.
