qiime longitudinal linear-mixed-effects --p-metric issue

Hi Carlo,

That's right — some special characters cause errors because they are interpreted as mathematical symbols in your formula!

no need to extract though. A couple solutions:

  1. (maybe) quoting the metric might work (this should work with the Artifact API and maybe quoting twice would work on the CLI, e.g., "'metric'")
  2. (definitely works) use qiime feature-table group to rename your metric(s) in the feature table, instead of extracting to manually rename.

Here's how to relabel (just apply to the feature axis instead of sample axis):
