Operational taxonomic unit (OTU)


OTUs (Operational Taxonomic Units)  are formed as part of the bioinformatory process from sequences (which are usually not more than 2% different from each other).


OTUs represent a sequence that can form a cluster of several thousand sequences. In bioinformatics, sequences that do not differ from each other by more than 2% are combined into one OTU.


OTUs are valuable:

In cases where no species-ID is possible, this can of course happen in the future.
