RT Journal Article SR Electronic T1 DADA2: High resolution sample inference from amplicon data JF bioRxiv FD Cold Spring Harbor Laboratory SP 024034 DO 10.1101/024034 A1 Benjamin J Callahan A1 Paul J McMurdie A1 Michael J Rosen A1 Andrew W Han A1 Amy Jo Johnson A1 Susan P Holmes YR 2015 UL http://biorxiv.org/content/early/2015/08/06/024034.abstract AB Microbial communities are commonly characterized by amplifying and sequencing target genes, but errors limit the precision of amplicon sequencing. We present DADA2, a software package that models and corrects amplicon errors. DADA2 identified more real variants than other methods in Illumina-sequenced mock communities, some differing by a single nucleotide, while outputting fewer spurious sequences. DADA2 analysis of vaginal samples revealed a diversity of Lactobacillus crispatus strains undetected by OTU methods.
