Hi All,
I’m using the picrust option in make.biom with great pleasure and no problems.
However, I’d like to track which of the original 97% clustered OTUs were converted to picrust-compatible Greengenes phylotypes. The output could be a two column matrix, where one column is the original OTUs, labeled Otu000001 … Otu038245, and the second column would contain a corresponding Greengenes ID. No Greengenes ID would mean the original OTU was not picrust-compatible. Seems straightforward. How can I make this dream a reality?
EDIT: is it just simply matching taxonomic classifications, perhaps to some level?
