Prediction performance of sPLS-DA for control vs. inoculated samples. Sparse partial least squares discriminating analysis (sPLS-DA) prediction performance of the testing set. Bands (Table S6) selected during model calibration using the training set for experiment one (Exp. 1; experiment with two treatments) and experiment two (Exp. 2; experiment with three treatments).

Experiment	No. components	BER	Proportion correctly classified
