You'll have to do this prior to training the classifier. There are two ways:

1. When running `rescript get-ncbi-data` you can set the taxonomic ranks you'd like to extract via the `--p-ranks` option. The default is to pull `kingdom phylum class order family genus species`. In your case you can use: `--p-ranks kingdom phylum class order family genus`
2. Perhaps more easily, you can simply make use of [rescript edit-taxonomy](https://forum.qiime2.org/t/processing-filtering-and-evaluating-the-silva-database-and-other-reference-sequence-data-with-rescript/15494#heading--sixteenth-header). That is, your command to remove the species labels may look something like this:

```auto
qiime rescript edit-taxonomy \
    --i-taxonomy NCBI-diatoms-rbcL-ref-tax.qza \
    --p-use-regex \
    --p-search-strings 's__.*' \
    --p-replacement-strings '' \
    --o-edited-taxonomy NCBI-diatoms-rbcL-ref-tax-genus-only.qza

```

Then use `NCBI-diatoms-rbcL-ref-tax-genus-only.qza` for all your downstream curation and classifier training steps. I hope I got the regex correct, but you can play around with it. 🙂

-Cheers!
