Fig. 4From: MetaMIS: a metagenomic microbial interaction simulator based on microbial community profilesPredicted microbial interactions show biological connections. a Positive interactions (black circles) were rich in metabolic complementarity. Negative interactions (white circles) generally showed lower levels of metabolic complementarity. b There were no differences of metabolic complementarity between the two groups in which positive or negative interactions were randomly selected. The error bar represented the standard error of metabolic complementarities for each groupBack to article page
