A word of caution: Since this release contains a very large number of samples and metabarcodes (ASVs), we encourage you to select a small number of samples, typically less than 3000. Additionally rather than using the interactive web application we encourage you to download and install the application on your computer using docker.

Please let us know of any problem you encounter with this release on GitHub.
