Fig. 4From: KrakenUniq: confident and fast metagenomics classification using unique k-mer countsDeeper sequencing depths require higher unique k-mer count thresholds to control the false-positive rate and achieve the best recall. A minimum threshold of about 2000 unique k-mer per a million reads gives the best results in this dataset (solid line in plot), see Additional file 3: Table S8 for more detailsBack to article page
