Fig. 2From: To denoise or to cluster, that is not the question: optimizing pipelines for COI metabarcoding and metaphylogeographyValues of the Entropy ratio (Er) of the set of ESVs obtained with the UNOISE3 algorithm at decreasing values of Ī± (a), and of those obtained with the DADA2 algorithm at decreasing values of omega_A (b). Arrows point at the selected value for each parameter. Horizontal blue line in (b) represents the Er value reached in (a)Ā at Ī±ā=ā5, horizontal red line marks the number of ESVs detected in (a)Ā at Ī±ā=ā5Back to article page
