Mapping of South American reads to PvPAM results in more primary and less chimaeric reads. Box plots show the number of primary (A) and chimaeric (truncated; B) reads (in millions) mapped to the PvPAM, PvW1 or PvP01 reference genomes. Reads originate from South American and non-South American Illumina WGS samples, which are shown separately. Outliers (< quartile 1–1.5*interquartile range; > quartile 3 + 1.5*interquartile range) are excluded from the plot for visibility. NS non-significant, * p < 0.05, ** p < 0.01, *** p < 0.001, **** p < 0.0001 (paired Wilcoxon signed-rank test). Next to the significance value, the % increase (+) or decrease (-) of mapped reads to PvPAM relative to PvP01 or PvW1 is shown. It is not possible to compare number of mapped reads between the South American and non-South American region, since those reads originate from different samples. n = number of Illumina WGS samples
