Using Rescript to exclude taxa

Hi there,
I am trying to design some 18S primers and would like to construct a database of all of the organisms that I do not want to hit.

Therefore I want to download data from SILVA but I want to exclude specific target taxa.

I have been looking at rescript and see that there are some taxa specific arguements, but can't figure out how to use this to exclude a target taxa when downloading data.

Any help appreciated.

Thanks

Hi @Alison_Waller, welcome to :qiime2:!

You can filter your sequences based on their taxonomy by using the qiime taxa filter-seqs ... command as outlined here.
