taxonomy confusion with s_

[Nicholas_Bokulich]

Hi @annsantos,
See here:

ASV collaps question

@shinseung, Those two labels are distinct: The first indicates that the sequence could not be classified beyond kingdom level (which probably indicates that it is really non-bacterial, e.g., host DNA). The second consists entirely of labels from the reference database you used. So QIIME is able to classify that sequence to the genus (or species?) level, but unfortunately the top match is to reference sequence(s) that are totally unannotated in the database. I hope that clarifies!

So no there is not really a way to see which species it is — it is in the reference database but the species label is unknown (probably because multiple species are too similar to differentiate with that marker).
