Issues with mmvec plug-in

Library Plugin Support
1

Hello,

I am trying to run the mmvec plug-in in qiiime2020.2 and keep getting the same error code:
Plugin error from mmvec:

'a' cannot be empty unless no samples are taken

from this command

qiime mmvec paired-omics
--i-microbes Bf2s2filteredtable.qza
--i-metabolites Ff2s2filteredtable2.qza
--p-summary-interval 1
--output-dir model_summary

My understanding of this error is that it is saying that the tables are empty but when I convert the files to .qzv I can see results so it can't be empty. Any ideas on what could be going on?

Hi, yes there are a couple of issues on the GitHub issuetracker with this error

Typically it is because all of the samples are getting filtered out, due to either the default filtering criteria (i.e. samples with less than 1000 reads being filtered out), or a mismatch between the two tables, or a mismatch with respect to the metadata.
