Hi there!
I would like to know how to merge all metazoans classified in different phyllum with Silva 138.
For example, merge “p__Cnidaria” and “p__Annelida” in a single category/level “Metazoa”.
Is it possible?
Thanks a lot
Hi @nfer,
Welcome to the forum! Sorry it has taken a few days for any moderators to respond — I think the issue is that it is not totally clear what you are trying to do, or if this is something that QIIME 2 can do.
If you are trying to group features in a feature table by taxonomy, you can use qiime taxa collapse
.
If you are trying to “fix” the taxonomic labels, this would be best done by manually modifying the taxonomy labels of your reference sequences prior to importing as a QIIME 2 artifact.
Similarly, you could export your taxonomy, manually modify, then import back into QIIME 2 and use qiime taxa collapse
to collapse your feature table (ASVs) into a new feature table where features are grouped by the modified taxonomy.
If none of the above are what you are looking for, then I am not totally sure this is something that QIIME 2 can do for you.
I hope that helps!
