  1. a Data were generated using cell counts to assign case versus control status (IFRACT = 0) and excluded the training data when scoring and running 10 10-fold cross-validations for functions 1–5 (ITRAIN = 0, FRACT = 0.1, NTIME = 10).
  2. b Total score is the summation over all scoring functions after linearly scaling the score for each individual function such that the top score is 50.0.
