Three IBD gut microbiota samples and their corresponding peaks’ relevance values illustrate unique sample-specific relevance ranking. All samples were correctly classified, with the classifier’s probability values displayed per sample. (a) Gut microbiota samples: peaks correspond to bacterial species; Peak heights correspond to abundance. Classification probability is shown to the right of each profile. (b) Relevance values calculated for each present peak in the profiles in (a). (c) Relevance values calculated for each absent peak (i.e. zero-valued peak) in the profiles in (a). (d) Average IBD gut microbiota profile across all samples. (e) Average healthy microbiota profile across all samples FAFV: Firmicutes, Actinobacteria, Fusobacteria and Verrucomicrobia; Relevance was calculated based on SVM predictions
