Build Status


Exact sample inference from high-throughput amplicon data. Resolves real variants differing by as little as one nucleotide. Visit the DADA2 website for the most detailed and up-to-date documentation.


The dada2 package binaries are available through Bioconductor:

## try http:// if https:// URLs are not supported
if (!requireNamespace("BiocManager", quietly=TRUE))

In order to install dada2 from source (and get the latest and greatest new features) see our installation from source instructions.
