REIMS analysis of faecal samples from different mouse strains. Negative ion REIMS mass spectra were acquired for faecal samples from three mouse strains (both sexes). LDA plot of first and second components. (a). The performance from a random forest classification is summarised in b. The distribution of the first and second linear discriminant components based on the 60 most informative m/z bins derived from principal component analysis c, d. Intensities of the five most discriminatory mass bins that drive strain segregation; large symbols are from individual samples that were misclassified
