Can I use other database for the taxonomic annotation?

Hi,
Can I replace greengenes database with other databases, like HOMD or ORALCore database for the taxonomic analysis? If yes, which file should I use for the classification and how can I convert *.fna into *.qza?

qiime tools import
–input-path sequences.fna
–output-path sequences.qza
–type ‘FeatureData[Sequence]’ ?

Thanks!

Hello,

Yes, you can use other databases! There is both an overview of how the taxonomic classifiers work and also a tutorial on training taxonomic classifiers, which covers how to build the *.qza file you need.

Let me know if this helps. Getting databases into the right format can be hard, so please post any question you have along the way.

Thanks so much! The databases worked well!
