Additional Information

Analysis of Positive Selection in Clinical Isolates *new*

• Analysis of dN/dS (omega) in two collections of Mtb clinical isolates using GenomegaMap (Window model) (see description of methods)
  • Moldova: 2,057 clinical isolates
  • global set: 5,195 clinical isolates from 15 other countries
• 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.
