  1. For each background NA subtype, the average d N /d S 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 d N and d S across all HA1 sites. Within tree samples, the site-averaged d N was divided by the site-averaged d S for that NA subtype, to obtain 1000 posterior estimates of the d N /d S ratio for each NA subtype background.
