Hi all. I am working with rumen metagenomics and struggling with the % of annotated reads with different databases.

I have downloaded HungateDB, CowRumen, and PlusPF (all in Kraken format) and have different % of mapping results.

I don't know if it is possible to merge databases. Is it? Or any idea on how to improve taxonomy%mapping?

Thanks a lot. Pablo

I'm interested in this also. I would like to merge PlusPF, and eupathdb48.

@Rohit-Satyam Yep! I used FlextaxD to merge the databases. https://github.com/FOI-Bioinformatics/flextaxd

Hi everyone, I believe this will be helpful to you.
