The theoretical ratios of observed to true total and shared k-mers. a Ratio of observed to true total k-mers, p t = n t /n t * (solid lines) and ratio of observed to true shared k-mers, p s  = n s /n s * (dashed lines), when k-mers are not filtered (Methods: Combined effects of coverage and sequencing error). k-mer lengths are k = 9 (red), 11 (orange), 13 (green), 15 (blue) and 17 (black). The simulation was performed with a sequencing error rate of 1 % and a read length of 76 bp, and the true distance between species is d = 0.1. b Like (a) but with filtering
