Figure 5. Sequence polymorphisms along the partial G protein of Argentine HMPV strains.

The horizontal axe represents codons position in the G protein and the vertical axe represents sequence polymorphisms expressed as nucleotide diversity Pi (π) estimated with DNAsp [19]. Argentine sequence polymorphisms for group A are indicated with gray bars and for group B with black bars. The black square for group B, and gray squares and rectangles for group A placed in the black bar situated at the top of graph indicate the codons, around which there are the potential B-linear epitopes predicted with BCPREDS [24]. Non overlapping windows of 14 amino acids in lengths were selected to perform comparable predictions with a specificity of 75% for both analyses.
