Figure 4: Bepipred Scores (B) for Amino Acid Positions of Influenza A Subtype HA Proteins. B values are shown only for those amino acid positions with a B value above the cutoff (B> 0.35). (a) HA (H1N1); (b) HA (H3N2); (c) HA(H6N1); (d) summed B scores (ΣB) for positions that are significant (>0.35) jointly for all three subtypes.
