BUG: SampleData[AlphaDiversity] -> Metadata doesn't work with tuples

Opened this issue · 1 comments

Bug Description
Some SampleData[AlphaDiversity] Artifacts contain tuples of numbers (for example, chao1). The transformer to qiime2.Metadata explodes when it sees this.

Steps to reproduce the behavior

  1. Produce a Chao1 SampleData[AlphaDiversity] Artifact.
  2. qiime metadata tabulate --m-input-file chao1_ci.qza --o-visualization chao1_ci.qzv
  3. See error

Expected behavior
Transforming SampleData[AlphaDiversity] to Metadata should work.

Questions

  1. Do we solve this in the transformer, or the format, or both, or neither?

This is an old issue, and one I suspect has been documented somewhere else, so if we ever find the xref, let's merge here into this issue.
