ω for subgroup 38.

Model M8 NEB values obtained from subgroup 43. Key position 3.29 is under positive selection (** denotes statistically significant posterior probability for ω>1). Two non-key positions, 2.56 and 2.60, have posterior probability exceeding 90% for positive selection. All positions with posterior probability for ω>1which exceed 0.5 are represented. Results of ω from the 10 key positions are also included. Key positions identified in Reference [13], [14] are indicated by X. Statistics of the 3 positions under positive selection are represented in bold italics.
