Exact sequence variants should replace operational taxonomic units in marker gene data analysis

B. J. Callahan, P. J. McMurdie, S. P. Holmes

The paper argues that exact sequence variants (SVs) should replace operational taxonomic units (OTUs) in marker gene analysis due to their higher resolution and better reproducibility.
