Converting a weighted region-to-region undirected connectome edge to weighted directed connectome edge. (A) Example undirected edge weight $\text{C}(\text{i},\text{j})$ that connects ROI $i$ and $j$. (B) Example directed edge weight $D(\text{i},\text{j})=h_j+\text{C}(\text{i},\text{j})$ from ROI $i$ to ROI $j$ where $h_j$ is a graph theoretic hubness value for ROI $j$ and $C(\text{i},\text{j})$ is the undirected edge weight value. (C) an example weighted undirected graph (i.e. connectome), and (D) is the weighted directed graph that is used to calculate our connectome dynamic. Note: R is short for ROI in the above illustration.
