Import RDP database to .qza file to use it with feature-classifier

[thermokarst]

Hey there @SLa!

@SLa

How can I get the classifier.qza based on this database?

Check out this quote from another post that came up on the forum when I searched for "RDP":

@Nicholas_Bokulich

There are lots of different reference databases out there, we can’t list them all . To figure out how to import the RDP database, just check out the formats of those SILVA or Greengenes file — it should be straightforward to reformat the RDP reference database for your needs. Then follow this tutorial to import and train a classifier with those files.

Check out that tutorial and let us know how it goes!

@SLa

are there big differences between RDP database and Greengenes?

There are almost certainly differences (two different approaches, two different databases, one has been updated more recently than the other), but as to how "big" those differences are, I can't say. Why don't you compare results produced by classifying against both databases? That would give you the confidence to stand by one DB vs another, in theory.
