Figure 4From: Deriving accurate microbiota profiles from human samples with low bacterial content through post-sequencing processing of Illumina MiSeq dataRelative abundance of presumed contamination and genuine signal plotted against amplicon concentration. Relative abundance of OTUs of sequencing artefacts (A-C) and non-artefacts (D-F) plotted against amplicon concentration following library preparation. Spearman’s rho (ρ) and significance of correlation are shown.Back to article page
