Reads mapping and analysis. Mapping and analysis of reads mapping to reference sequence datasets. (A) The distribution of reads mapping to each reference dataset. (B) Reads mapping to each of the three reference datasets and the overlaps between them. (C) Distribution of reads mapping to the viral reference datasets. The horizontal axis depicts the 3735 viral genomes while the vertical axis depicts the reads mapping to each of the viral genomes. The reads that map to Japanese encephalitis virus was ordered different from the reads that mapped to the next highest.
