pAA,pNT,pS, and pN, represent the average number of amino acid, nucleotide, synonymous and non-synonymous nucleotide differences per site along with the Z-test of selection. SE indicates standard error based on 1000 bootstrap replicates.
aaverage transition/transversion ratio.
#calculated using Maximum composite likelihood method in this case.
