In one hand, I have OTU data from 16S, which can be graphed in a cladogram-like format. (My colleague generates this.)
On the other hand, I have species counts, which can be graphed as a cladogram.
I want to do a fair side-by-side comparison.
I am pretty sure we can't convert OTU to species or genera with 100% certainty.
However, it seems if OTU are predefined, then there should be a mapping somewhere of species to OTU. Is this possible? How would I do it?
