# Speciesprofile

$D_{SpeciesProfile} = \sqrt{ \sum_{j=1}^{S_T} \left ( \frac{S_{Aj}}{S_{A+}} - \frac{S_{Bj}}{S_{B+}} \right )^2 }$
• where $S_{Aj}$ is the abundance of sample A in the jth OTU
• where $S_{Bj}$ is the abundance of sample B in the jth OTU
• where $S_{A+}$ denotes the total abundance of sample A
• where $S_{B+}$ denotes the total abundance of sample B
