  1. aChao1/Ace richness estimator: the total number of OTUs estimated by infinite sampling. A higher number indicates higher richness.
  2. bSimpson/Shannon diversity index: an index to characterize species diversity. A higher value represents more diversity.
  3. cGood’s coverage: estimated probability that the next read will belong to an OTU that has already been found.
