Hi Gang,

Sorry for the confusion. So I used coordinates from Power et al. 2011 (https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3222858/) to create nodes for the default mode network, salience network, and frontoparietal network based on resting-state functional data which were collected for both pre- and post-intervention. The default mode network has 59 ROIs, salience network 18 ROIs, and frontoparietal network 25 ROIs (so 102 ROIs in total). I ran 3dNetCorr using these ROIs and have a full and symmetric matrix (z score) for these ROIs (102 x 102) for each subject. Within network means averaging z score between the same network - for example, z score between ROI #1 to # 59 for the default mode network. Between network means averaging z score between different network - for example, z score between the default mode network nodes and salience network nodes.

Please let me know if you need more infromation.

Best,
JW
