Data from "Consistent negative selection constraints at protein-coding sites across broad evolutionary time-scales" by Khurana et al
Omega (dN/dS) values for all coding sites in Gencodev3b computed from 28 whole-genome vertebrate alignments using PAML. omega values for all codons
Omega values for sites identified as being under positive selection in humans relative to vertebrates (omega > 1 and probability (omega>1) > 0.5) Codons under positive selection
