LegATo is a suite of open-source software tools for longitudinal microbiome analysis. It is extendable toseveral different study forms with optimal ease-of-use for researchers. Microbiome time-series datapresents distinct challenges including complex covariate dependencies and variety of longitudinal studydesigns. This toolkit will allow researchers to determine which microbial taxa are affected over time byperturbations such as onset of disease or lifestyle choices, and to predict the effects of these perturbationsover time, including changes in composition or stability of commensal bacteria.

LegATo integrates visualization, modeling and testing procedures. It is currently in development, but it will soon be supplemented by hierarchical clustering tools and multivariate generalized estimating equations (JGEEs) to adjust for the compositional nature of microbiome data.

In music, legato indicates that notes are played or sung smoothly and connected over time, without a noticeable break between them.

The LegATo package facilitates a cohesive and interconnected understanding of longitudinally-collected sequencing samples, much like the smooth connection of musical notes in a legato passage.
