Figure 2. Total numbers of minority variant positions in all sequenced VZV samples.

Each bar indicates the number of genome positions at which multiple alleles are present (minor allele frequency 5–49.9%). Datasets are normalised (corrected for the total number of mapped reads per sample) and showed no evidence that minority reads map to specific regions of the genome or that any bias between the proportions occurring in coding and non–coding regions of the genomes is present. Viral genome copies, post-target enrichment could not be determined for some samples (nd).
