No feature classifier output

I am a new user if qiime2. I have trained a classifier using the silva db for 16S (97%), To assign taxonomy to my sequences I am using

qiime feature-classifier classify-sklearn --i-classifier classifier-16S-silva-97.qza --i-reads rep-seqs-deblur2c.qza --o-classification tax_4000_97.qza

The script appears to run (takes about 30 min) and does not produce any errors, but there is no output file. Would an output file be produced if no sequences were classified? I am not sure how to proceed.

Hi @EWT!

The Taxonomy formats should error when saving if they are empty (no taxonomy records in the file).

Can you provide the following information so that we can get to the bottom of this?

  • The version of QIIME 2 that you are using
  • The output of the above command when run with the --verbose flag
  • In your analysis directory, please run the following command (and copy-and-paste the full results here):
$ ls -lah

Thanks! :t_rex:

It turns out I was not patient enough. The program ran for 3 days before returning the file.
