Long story short, I’m interested in creating some tools that can allow for different types of metadata to be merged together. Here are some use cases (for biplots)
- Visualizing a biplot with feature metadata such the taxonomies. Doing so requires that you merge / create a metadata table of features.
- Visualizing genome presence / absence on a biplot, but to do so requires you to have something like genome prediction from picrust to be converted to metadata.
- Visualizing differential abundance values (from something like DEseq2, aldex2, stray, …) directly on a biplot.
- Any of the above tasks also apply to phylogenetic tree visualization
I know that Metadata object are now Artifacts. However, I have not seen any examples of plugins outputting metadata. Do these examples exist, or is there additional infrastructure required to make this happen?
