Hi!

I have received from a collaborator feature table, with feature names already being taxonomy ( e.g k__Bacteria;p__Actinobacteria;c__;o__;f__;g__;s__;Other). So, I don't have a FeatureData[Taxonomy] artifact. Is there any way to still run the command?

Thanks!

Hello!
You can create a taxonomy file as a tsv table, in which you have two columns - Feature ID and Taxon. Then duplicate your IDs from feature table, so both columns in your taxonomy file contain the same information. Then you can import it to Qiime2 (check importing tutorial).
Using taxonomy file you will be able to collapse further your table to lower taxonomy units, such as genera, family, order and so on.
