What it does
============

Calculates the number of "core" OTUs shared by groups given thresholds for how
frequent the OTUs should be above a certain abundance. Also returns the average
abundance of the OTUs in a particular group.

The Galaxy tool calls the `amp_venn
<https://madsalbertsen.github.io/ampvis2/reference/amp_venn.html>`_ function
of the ampvis2 package.
