Update of Greengenes

Hi! I do not now whether this has already been asked. I have searched for it but did not find anything.

Until now, I have been using SILVA database for performing taxonomy classification. However, I just have seen that Greengenes has been updated to Greengenes2. After reading the article (10.1101/2022.12.19.520774), I supposed using this database is highly recomended right?

Hope anyone can help me with this doubt.

Kind regards,
Jorge Garcia

Here's the GreenGenes2 forums announcement.

SILVA is still commonly used and performs well. You could try both and see what works better on the positive controls you included on the run.
