#' This tutorial explores the dataset from Tengeler et al. (2020) available in the `mia` package.
#' obtained using `mia::makePhyloseqFromTreeSE(Tengeler2020)`
#'
#' This is a phyloseq version of the Tengeler2020 dataset.
#'
#' Tengeler2020 includes gut microbiota profiles of 27 persons with ADHD.
#' A standard bioinformatic and statistical analysis done to demonstrate that altered microbial
#' composition could be a driver of altered brain structure and function and concomitant changes
#' in the animals behavior. This was investigated by colonizing young, male,
#' germ-free C57BL/6JOlaHsd mice with microbiota from individuals with and without ADHD.
