I am having an issue trying to obtain get the sample-classifier heatmap output annotated with taxonomy intead of feature IDs.
I tried collapsing the feature table and using this collapsed table as input but it does not work.
The command I am running is this one:
qiime sample-classifier heatmap /
–i-table collapsed-table-species-level.qza /
–i-importance sample-classifier-prediction-results/feature_importance.qza / --m-metadata-file metadata-comb-rep1-rep2.tsv /
–m-metadata-column Diagnostic /
–p-feature-count 100 /
–o-heatmap heatmap.qzv /
And then the output is this:
Plugin error from sample-classifier:
Cannot group an empty table.
Debug info has been saved to /tmp/qiime2-q2cli-err-dzsqdsrz.log
Any ideas what might be going wrong?
