From: QQ-SNV: single nucleotide variant detection at low frequency by comparing the quality quantiles
QQ-SNV vs. other methods: computational efficiency on HCV plasmid mixture datasets. On the x-axis is the coverage, which is the average number of reads per position. On the y-axis is the computation time in minutes. A reference line is shown at 5 and 60 min. The size of the data points (reads 1, reads 2 and reads 1 + 2) shown for the different HCV datasets corresponds to the variant percentage (0.5 %, 1 %, 2 % and 10 %)
