+from high-throughput amplicon sequencing data, replacing the coarser and less
+accurate OTU clustering approach.  The dada2 pipeline takes as input
+demultiplexed fastq files, and outputs the sequence variants and their
+sample-wise abundances after removing substitution and chimera errors.
+Taxonomic classification is available via a native implementation of the RDP
+naive Bayesian classifier, and species-level assignment to 16S rRNA gene
+fragments by exact matching.")
