Observed_otus error

I made observed_otus_vector.qza using --p-metric osd.
And then I tried the commands below to make tsv for having OTUs values. But I got an error.
How can I convert it to tsv? Or are there other ways I can see the number of OTUs of my samples?


qiime diversity alpha-group-significance \

--i-alpha-diversity core-metrics-results/observed_otus_vector.qza
--m-metadata-file sample-metadata.tsv
--o-visualization core-metrics-results/observed_otus_vector.qzv

Plugin error from diversity:
Non-numeric values detected in alpha diversity estimates.

Hi @lion ,

You could also export your data (see qiime tools export --help) to view the raw values. Or use qiime metadata tabulate to view as a QZV.

Good luck!
