I have been generating OTUs at multiple different identity levels (via qiime) to see the effect on otu numbers and diversity and I want to relate it to taxonomic levels.
In the past I have generally followed that roughly (ROUGHLY):
- 97% ~ Genus
- 94% ~ Family
- 88% ~ Order
But I wouldn't put my want to sign my name to that. Does anyone have any experience or references to this effect?
