Graphical representation of the likelihood-based optimal model for the nuclear SSU rRNA dataset. The optimal model for the nuclear SSU rRNA dataset, as obtained by both the likelihood-based and the extended clustering approach, has 6 clusters: the red cluster contains 2 contexts: AXG and GXG, the green clusters contains 2 contexts: TXC and TXG, the light blue cluster contains 3 contexts: AXA, AXT and GXT, the yellow cluster contains 2 contexts: CXG and GXC, the purple cluster contains 5 contexts: AXC, CXC, GXA, TXA and TXT, and the orange cluster contains 2 contexts: CXA and CXT.
