Can I view the abundance distributions of a particular feature across all samples in the PCoA plot?

Yes, MicrobiomeAnalyst allows users to color samples based on their alpha diversities or the abundance level of a feature of interest. To do so, users need to

  1. Select “Beta-diversity analysis” from the Analysis Overview.
  2. First select a taxonomic level (i.e. Genus), and select the feature of interest (i.e. g__Bacteroides), see below
  3. Click the “Update” button. An example output is given below. It is clear that the feature abundance is strongly associated with the patterns of sample distribution
