Hello Stephanie,
As we are looking specifically at L.crispatus in our research, is there any way I can find out what the bulk of k__Bacteria;p__Bacillota;c__Bacilli;o__Lactobacillales;f__Lactobacillaceae;g__Lactobacillus;__
in the taxa barplot actually consists of (whether it is one dominant Feature ID or an accumulation of Feature IDs that share the similar taxon k__Bacteria;p__Bacillota;c__Bacilli;o__Lactobacillales;f__Lactobacillaceae;g__Lactobacillus;__ in taxonomy.qza)?
You could export the taxonomy and features and then merge them back together.
That should give you a list of all ASVs and the taxonomy of each one. So you can see if that g__Lactobacillus is coming from a single ASV or a whole bunch of them, just like you described!
