Taxa bar plot; Plugin error 'Float64Index'


I am receiving an error message when I am trying to generate the interactive taxa bar plots

(qiime2-2018.2) [email protected]:~/Lyndsay/qiime_taxa$ qiime taxa barplot --i-table dada2-table.qza --i-taxonomy taxonomy.qza --m-metadata-file metadata.tsv --o-visualization taxa-bar-plots.qzv
Plugin error from taxa:

unhashable type: ‘Float64Index’

I’ve looked at a previous post with a simillar issue but I’m not really sure how to try and fix this.
Any help or advice would be appreciated.


Hi @lec49! We have seen this error come up before (see here for open issue) - this happens when there are no overlapping feature ids between your feature table and you taxonomy. Double check those files to make sure that you aren’t provided a collapsed table as input. Was your taxonomy generated using the same rep-seqs that came from the same DADA2 run that your feature table came from? If you are are still having problems after looking into that, please send us links to download your input files necessary for us to re-run the failing command you provided about. Thanks! :t_rex:

Hi @thermokarst

Thanks for the reply. I have looked into this and the table is not collapsed. Yes everything was generated from the same rep-seqs. I have attached a link to the input files.

taxonomy.qza (43.9 KB)
metadata.tsv (264 Bytes)
dada2-table.qza (72.5 KB)

Hi @lec49!

I don't think that is the case - using provenance I just double checked - your table and your representative sequences came from two different DADA2 runs (actually, they came from two completely different data sets - see below):

feature table:

representative sequences:

Your trimming and truncation parameters are different between runs, which will impact the downstream artifacts.

Looking at the provenance, it looks like the table was generated from already demultiplexed paired-end data, while the representative sequences were generated from EMP-formatted single-end data that was demuxed in QIIME 2 (also, using a super old version of QIIME 2 - 2.0.6).

So, double check that your files are all in order, because it looks like you are mixing at least two different analyses here. Keep us posted!

PS - provenance is awesome! :t_rex: :t_rex: :t_rex:
