For each branch, the 1, 5, 10, 50, and 100 genes with the highest absolute ΔGLS values were excluded; we also excluded the genes with outlier ΔGLS values (the number of outlier genes is given above the corresponding bar for each branch). The Y-axis shows the difference in log-likelihood scores (ΔlnL) for the favored topological hypothesis. The different hypotheses favored are indicated by different bar colors; red bars denotes that ML trees inferred from their corresponding data matrices support T1; green bars denote ML trees supporting T2; gray bars denote ML trees supporting hypotheses other than T1 and T2. The ΔlnL values displayed on the Y-axis corresponds to the difference in log-likelihood values for T1 against either T2 or “others”. If ΔlnL is > 0, then the ML tree supports T1, whereas if ΔlnL is < 0, then ML tree supports T2 or “others”.
