Taxonomic Analysis error

Hello Qiime2 users,
I encounter an error after Taxonomic analysis. I could see only Bacteria (kingdom level) as an attachment "

". and same situation with taxa-bar-plot. I used same grrengenes database v13.8 which is available in tutorial and could not find any option to select the level of taxonomy.

Kindly help me to solve this error.


Hi @khemlalnirmalkar!

The tutorial explicitly states not to use those pre-trained classifiers for real data - they are for demo purposes only. You can get your hands on some production-ready pre-trained classifiers here.

If you are still having issues after re-running with a full pre-trained classifer, please provide the following:

  • The version of QIIME 2 you are using
  • The classifier you are using
  • What does your sequencing data represent? As in, 16S, ITS, something else?
  • Which variable region(s) did you amplify to produce the sequencing data? Which primers did you use?
  • What was the exact command you ran? Copy and paste please.

Thanks! :t_rex:

Hello @thermokarst Thank you so much for your tips. Now it’s working well.
