Benchmarks of OTU picking tools on natural communities. Benchmarks of OTU picking tools on natural communities. (A) Stability analysis on experimental technical repeats. Data indicate fractions of overlapping sOTUs from two technical replicates in all OTUs as a function of the minimal frequency threshold present in one of the repeats. (B and C) Application of Deblur in the howler monkey data set. (B) Fraction of sequences matching entries in the NCBI nr/nt database (as of 1 December 2016) with 0.1 or 2 mismatches (red, green, or blue, respectively) from sOTUs unique to Deblur or to DADA2 or present in both (left to right). (C) Heat maps showing sOTUs (rows) in common with Deblur and DADA2, as well as those unique to Deblur and DADA2 (bottom, middle, and top rows, respectively). Samples (columns) are sorted by species and habitat. A total of 200 sOTUs per group (i.e., common, unique to Deblur, or unique to DADA2) were randomly selected for visualization purposes. (D) Single-threaded runtime comparison of Deblur, DADA2, and UNOISE2 against one of the stability MiSeq runs at increasing numbers of samples.
