I have a question about my taxa bar plot: Why do I have a group that has no phylum when I select level 2 for taxonomic level? The other groups are ascomycota, basidiomycota, etc and an unidentified phylum which is fine, however one group is just named "k__Fungi;__"
Any ideas as to why this happened and why this was not grouped with unidentified?
If it's any help, I trained my own classifier using the UNITE dynamic reference file (version 8.0, Nov. 18, 2018) by following the moving pictures tutorial.
Thank you and happy holidays!
