Amplicon Sequence Variant (ASV) is a term used to refer to individual DNA sequences after applying a denoising algorithm, such as DADA2.[1] ASVs are largely replacing the more traditional Operational Taxonomic Units (OTUs) generated by clustering to some similarity threshold with software such as QIIME.[2]
