Metabolic classifiers and shifts within the irradiated metabolome. a Heatmap of per-group indicator values (distance-based redundancy analysis; db-RDA) for selected condition-specific features. The total number of condition-specific features (out of a total of ~ 4500) is highlighted. b Enrichment analysis of condition-specific putatively annotated metabolites in metabolite classes from the HMDB chemical taxonomy database. Over-represented classes (red) are those with higher relative presence in the set of condition-specific metabolites as compared to the entire metabolomics dataset (respectively lower for under-represented classes in green). Circle size is proportional to the (unsigned) fold ratio between those relative abundances
