  1. Additional class discriminating features retrieved using MetaFIND after initial PLS-DA, VIP cut-off ≥ 6, and Random Forest (RF) feature selection for the Brain Stem vs. Cerebellum class comparison (which returned 41 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.
