Figure 2From: Unsupervised statistical clustering of environmental shotgun sequencesFragment likelihood separation. Log likelihood values of fragments from pairs of species according to models fitted by the classifier. Points' positions on the two axes represent log likelihoods of each fragment according to the first and second model, respectively. A, Helicobacter acinonychis vs. Vibrio fischeri, good separation (98% accuracy, D = 1.31); B, Streptococcus pneumoniae vs. Streptococcus pyogenes, poor separation (57% accuracy, D = 0.22). Fragment length was 800 in both cases. 500 fragments per species were supplied.Back to article page
