Otu
OTU is an acronym that can refer to more than one concept in science and engineering. In biology and ecology, an Operational Taxonomic Unit is a term used to categorize microorganisms or other organisms based on DNA sequence similarity, serving as a practical proxy for species in environmental sequencing studies.
OTU clustering groups sequences into operational units by similarity, typically using a threshold around 97% for
The approach has limitations: similarity thresholds are arbitrary, outcomes depend on sequencing quality and target gene,
In telecommunications, OTU stands for Optical Transport Unit, a framing structure used in the Optical Transport
