Consensus tree of 17 dengue 4 env sequences The consensus tree for the example analysis of Dengue 4 sequences under the strict clock analysis with a GTR + CP substitution model. Each internal node is labeled with the posterior probability of monophyly of the corresponding clade. The gray bars illustrated the extent of the 95% highest posterior density intervals for each divergence time. The scale is in years.
