Fig. 1From: Revealing the microbial assemblage structure in the human gut microbiome using latent Dirichlet allocationSchematic illustration of microbial assemblages and cluster analysis for the human gut microbiome, where A, B, and C indicate microbial assemblages, with circle size indicating abundance. The cluster of each individual is determined by the dominant assemblage. However, a cluster analysis cannot capture the non-dominant but shared microbes among samples, such as those comprising assemblage CBack to article page
