New user. Both the feature-volatility and maturity-index pipelines generate featuredata[importance] artifacts, but a forum search did not indicate what they were for or how to visualize them, and a qiime2 search just gives me a donut of death. What purpose does the featuredata[importance] artifact serve?
Welcome to the forum @bill!
This is described in this tutorial:
and a little more about how to interact with that here:
The short answer is: this contains feature importance scores. You can use
qiime metadata tabulate to view and rank features by importance score. This is useful for the maturity-index (tells you which features are most predictive of age), but no need with feature-volatility; the volatility visualization already has an interactive barplot that ranks features by importance score.
Sorry you ran into issues with the donut of death; fixing this is on our radar, see here:
Thank you Nicholas. One problem is that when I run ‘qiime featuredata --help’ I get the reply ’ Error: QIIME 2 has no plugin/command named ‘featuredata’.
There is no such plugin. When in doubt, check out the tutorials and documentation at qiime2.org for information on different artifact types etc.
