Top left: a spring embedded layout of the areal graph at 4% tie density visualizing the graph and the basis for subgraphs. Top right: for both cohorts, plots are shown of the areal assignments into subgraphs (colors) at tie densities from 10% down to 2% in 1% steps. ROI ordering is identical, and all subgraphs with fewer than 4 members are colored white. The standard measure of subgraph similarity, normalized mutual information, between node assignments of the cohorts at identical tie densities ranged from 0.86-0.92, indicating highly similar patterns across cohorts (1 = identical assignments, 0 = no information shared between assignments). Bottom: subgraphs from three thresholds are shown for the areal (spheres) and modified voxelwise graphs (surfaces). Note the similarity of subgraph assignments beteween networks, despite the great difference in network size and cortical coverage, even in different subjects (main vs replication cohorts). All areal subgraphs with fewer than 4 members are colored white, and all modified voxelwise subgraphs with fewer than 100 voxels are colored white. Areal networks are shown at 10%, 3%, and 2% tie density (r > 0.16, 0.30, and 0.33), and modified voxelwise networks are shown at 5%, 2%, and 0.5% tie density (r > 0.16, 0.23, and 0.31).
