Table 4. . Linear correlation coefficients, r, for unweighted and weighted graph metric rank consistency using varying dilation and streamline count settings (fixed atlas scale at Scale 60). The correlation coefficients are derived from the same procedure described in Figure 5 and Table 3. In each entry, the first coefficient corresponds to the unweighted metric, and the second one corresponds to the weighted metric. For varying dilation, the SC is fixed at 10⁶; and for varying SC, dilation is fixed at D0. Both dilation and streamline count have little effect on the unweighted modularity rank, though the weighted modularity is noticeably affected by dilation. Assortativity rank is mildly affected by dilation and streamline count. Clustering coefficient rank is robust against dilation change, and is noticeably affected by streamline count. Overall, the effect of dilation or streamline count on graph metric rank is less significant than that of atlas scale change.
