See details. DADA2 is a de novo method, and completely reference free. 16S rRNA gene sequencing raw data was processed using QIIME2 version 2019-1 [] as follows. (see last line of code below) and then used that information to assign colors based on phylum (see above). Visualize the samples at *Level 2* (which corresponds to the phylum level in this analysis), and then sort the samples by ``body-site``, then by ``subject``, and then by ``days-since-experiment-start``. Recent years have seen this classical term evolving into sOTU, where every exact 16S sequence is treated as the basic unit (i.e., an sOTU), hence improving resolution.
