  1. Represented below are the initial features selected by PLS-DA (VIP cut-off ≥ 1) and Random Forest (RF) feature selection techniques, denoted by FS for classes Day 1 vs. Day 3 and Day 3 vs. Day 5 in Dataset 1. Also represented in bold are the additional features discovered by MetaFIND, denoted by MF. The asterisk signifies those additional features discovered by MetaFIND that were identified as being representative of all or part of a class discriminating metabolite. The original VIP scores/RF Importance Rank (Imp. Rank) of the features discovered by MetaFIND are also given.
