Analysis of dN/dS (omega) in a global collection of 10k Mtb clinical isolates using GenomegaMap (Window model)
clinical isolates collection: global set of 10,626 Mtb genomes
In the omega plots, the black line shows the mean estimate of omega (dN/dS) at each codon, and the blue lines are the bounds for the 95% credible interval (95%CI, from MCMC sampling).
A gene is under significant positive selection if the lower-bound of the 95%CI of omega (lower blue line) exceeds 1.0 at any codon.
