Plugin error from taxa barplot

Hi, Im having an issue when trying to plot my bar plot according to my frequency table, reference taxonomy, and metadata. The error looks like this:

Plugin error from taxa:
unhashable type: 'Float64Index'
Debug info has been saved to /tmp/qiime2-q2cli-err-9ew1sauo.log

my command was as follows:

qiime taxa barplot
--i-table table2.qza
--i-taxonomy classifier-taxonomy-test.qza
--m-metadata-file metadatafinal.tsv
--o-visualization taxa-bar-plots.qzv

the error log looks like this:

Not really sure how to proceed from here. I have attached the files as well. Any direction you could give would be greatly appreciated. Thankstable2.qza (54.3 KB)
metadatafinal.tsv (65.2 KB)
classifier-taxonomy-test.qza (1.1 MB)

Hi @pnayak!

This looks very similar to another recent thread:

I ran feature-table summarize and metadata tabulate on table2.qza and classifier-taxonomy-test.qza, respectively. It looks like none of the feature IDs in your feature table are present in your taxonomy annotations:

Is it possible you mixed some files up somewhere along the way? You can double-check using provenance, if that helps at all.

Also, a quick note, we have a major overhaul to metadata coming up soon, your current metadata file will not work moving forward, because you have duplicate identifier column labels (#SampleID and SampleID). Check out this post for more info on these upcoming changes:

Keep us posted, thanks! :t_rex:


Open issue for cleaning up this error message.

Ah I see, I created the taxonomic classifier using the wrong reference-seqs file. I have used the right file and I have gotten the plot without error. Thanks very much, I really appreciate the help :slight_smile:

In the QIIME 2 2018.2 release, the changes to Metadata column headers that @thermokarst described are now in effect.

There are a number of other changes to QIIME 2 Metadata in the 2018.2 release. See this forum announcement for details on what changed, as well as the updated Metadata tutorial. :sun_with_face:
