    Snippet: Phylogenetic analysis. We downloaded all (n Ï­ 92) available fulllength genome sequences of MERS-CoV from GenBank and used RAxML (20) for phylogenetic analyses of the complete genome, the ORF1ab gene, and the S gene, respectively. One thousand bootstrap replicates were run. Furthermore, the Bayesian Markov chain Monte Carlo method, implemented in BEAST (21) , was used to estimate the time to the most recent common ancestor.

    Document: Phylogenetic analysis. We downloaded all (n Ï­ 92) available fulllength genome sequences of MERS-CoV from GenBank and used RAxML (20) for phylogenetic analyses of the complete genome, the ORF1ab gene, and the S gene, respectively. One thousand bootstrap replicates were run. Furthermore, the Bayesian Markov chain Monte Carlo method, implemented in BEAST (21) , was used to estimate the time to the most recent common ancestor. Twelve different model combinations were applied. For all the analyses, we used the general time-reversible nucleotide substitution model with gamma-distributed rate heterogeneity. Bayesian Markov chain Monte Carlo analysis was run for 50 million steps. Trees and parameters were sampled every 5,000 steps, with the first 10% removed as burn-in.
