Average dN/dS across the H7 avian influenza HA1 on different NA backgrounds
Subtype Mean dN/dS Lower 90% HPD limit for dN/dS Upper 90% HPD limit for dN/dS
H7N1 0.107 0.063 0.156
H7N2 0.226 0.126 0.309
H7N3 0.102 0.067 0.137
H7N7 0.120 0.074 0.168

For each background NA subtype, the average dN/dS across the HA1 coding region was obtained for each MCMC sample by first averaging over mutational mapping replicates on that tree, then calculating average values for dN and dS across all HA1 sites. Within tree samples, the site-averaged dN was divided by the site-averaged dS for that NA subtype, to obtain 1000 posterior estimates of the dN/dS ratio for each NA subtype background.
