Table 2 Read mapping statistics for Illumina (A) and nanopore libraries prepared with REPLI-g (B) and Sigma (C) WTA protocols. Reads were mapped using BWA-MEM with default settings (Illumina) or nanopore-specific (-x ont2d) settings. Columns are, respectively, NCBI accession numbers for each VEEV reference genome shown; total number of reads mapped to each reference; number of non-specific matches, number of perfect matches, average depth of coverage of non-zero coverage regions, percentage of reference genome covered by at least 1 read; number of regions in the reference with zero coverage; and total length of zero coverage regions.
