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

Calculate alpha-diversity indices for each sample and combines with the metadata.

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

Usage
=====

The alpha-diversity indices are calculated per sample using the vegan function `diversity <https://rdrr.io/pkg/vegan/man/diversity.html>`_,
where the read abundances are first rarefied using `rrarefy <https://rdrr.io/pkg/vegan/man/rarefy.html>`_ by the size of the rarefy argument.
Refer to the vegan documentation for details about the different indices and how they are
calculated.


Input
=====

@HELP_RDS_INPUT@

Output
======

A tabular dataset containing the chosen alpha-diversity measures per sample.
