Figure 2.
Comparison of mapped reads in different samples of 4 selected HPV types. Each panel shows the number of mapped reads (in vertical) of 5, 5, 4, or 3 samples detected in corresponding HPV types (NCBI accession number is shown). The vertical axis marked with “*” in HPV16 is shown in logarithm scale to clarify marked nucleotide variant sites. The peak number of reads per sample is shown at the left. The sample is shown at the right. Vertical lines in colors indicate sequence differences. Triangle marks show distinctive or absent variant sites.
