For Structure, the probability of each K given the data (Pr(K|X)) was calculated using the ad hoc method described by Pritchard et al. [39]. The optimal number of K was also determined using the ΔK method of Evanno et al. [40]. For the Structurama we present the posterior probability assuming a gamma hyper-prior G(2.5,0.5)
