Once you have the manifest file, `DrT_Qiime2.sh`, and fastq.gz in a directory, you can run the script. All the steps are wrapped in a single script, including the importing the data, denoising, trimming, joining, table ASVs, tree, and basic diverstiy analysis. The script also has the steps to convert QIIME2 artifacts into visualization files, which you can view using qiime tools view or <a href="https://view.qiime2.org">here</a>.
