HMP correlation networks inferred using SparCC.

<p>Networks inferred using SparCC from the same data as in <a href="http://www.ploscompbiol.org/article/info:doi/10.1371/journal.pcbi.1002687#pcbi-1002687-g001" target="_blank">Fig. 1</a> (see <a href="http://www.ploscompbiol.org/article/info:doi/10.1371/journal.pcbi.1002687#pcbi.1002687.s003" target="_blank">Fig. S2</a> for SparCC networks of all HMP body sites). No correlations with magnitude greater than the 0.3 cutoff were inferred from the shuffled data (not shown). Nodes represent OTUs, with size reflecting the OTU's average fraction in the community, and color corresponding to the phylum to which the OTU belongs. Edges between nodes represent correlations between the nodes they connect, with edge width and shade indicating the correlation magnitude, and green and red colors indicating positive and negative correlations, respectively. For clarity, only edges corresponding to correlations whose magnitude is greater than 0.3 are drawn, and unconnected nodes are omitted.
