For each gene, the table indicates the total number of data sets studied (both databases), the total number of networks generated by TCS, the total number and mean (per network) of reticulate nodes and the number of networks classified as tree, galled-tree, tree-child, and tree-sibling. In parenthesis we indicate the number of networks in that category that did not belong to the previous category and the percentage of characterized networks. In brackets we indicated the number and mean (per network) of reticulate nodes. The last row indicates the number of uncharacterizable networks (i.e., more complex than tree-sibling).
