  1. Additional class discriminating features recommended by MetaFIND after initial PLS-DA, VIP cut-off ≥ 5, and Random Forest (RF) feature selection for the Brain Stem vs. Hippocampus class comparison (which returned 32 and 100 features respectively). The MetaFIND column shows class discriminating features that were retrieved using the MetaFIND application. An asterisk signifies that the feature represents part of a metabolite with a known assignment. The original VIP scores/RF Importance Rank (Imp. Rank) of the features discovered by MetaFIND are also given.
