From: Deriving enzymatic and taxonomic signatures of metagenomes from short read data
SPSR test on artificial metagenomes. SPSR tests, based on normalized factors derived from the training set. Shown are predicted and known numbers of enzymatic genes relative to predicted and known aaRS enzymes (EC = 6.1.1). Error-bars reflect the standard deviations of the factors derived from 15 trials of the artificial super-organisms. Shown here is a comparison of predicted relative amounts of EC = 1.1.1 enzymes for 11 artificial metagenomes containing 7 species from the test set. EC = 1.1.1 is a leading EC category containing alcohol dehydrogenases with NAD+ or NADP+ as acceptor. The results imply a good generalization for metagenomes composed of 7 bacteria.
