Extended Data Fig. 4: Metabolomics-derived coarse-grained resource groups.
From: Resource competition predicts assembly of gut bacterial communities in vitro
(a) The structure of metabolomics-derived coarse-grained resource groups. A metabolomic feature was considered depleted if it decreased by >100-fold compared to fresh medium, and features that shared the same set of depleting species were grouped together into a coarse-grained resource group, shown as one column in the matrix. The number of features in each resource group is shown in the bar plot above each column. Only groups with more than one constituent feature are shown. (b) The cumulative fraction of the number of metabolomic features as a function of the number of coarse-grained resource groups included, starting with the leftmost column in (a).
