FIG. 1.

Similarity plots of the aligned paramyxoviruses' genomes. The plots were obtained using an in-house program based on multiple alignments of viral genomes from 29 different strains in the Paramyxoviridae (A), 22 different strains in the Paramyxovirinae (B), and 7 different strains in the Pneumovirinae (C). The identity percentage score given on the y axis was calculated based on the exact-match percentage with a window of 25 nucleotide positions, and the window was progressively moved across the alignment in 1-nucleotide-position steps. The x axis shows the first position of the window in the multiple alignments of the viral genomes.
