Performance evaluation.

Classifier	Level	Sp (%)	Sn (%)	ACC (%)	Pre (%)	MCC (%)
Phos-based	High	94.8	70.0	88.3	83.8	69.0
	Medium	90.0	77.8	86.7	74.2	66.8
	Low	85.0	82.0	84.2	66.9	63.2
YinOYang ∗1	∖	75.5	42.7	68.9	67.5	32.7
O-GlcNAc-based	High	94.9	50.4	83.0	78.8	63.3
	Medium	90.0	57.3	81.2	67.9	50.0
	Low	85.2	70.2	81.0	63.3	53.5
YinOYang ∗2	∖	71.2	42.7	56.8	59.6	14.8

For YinOYang ∗1 and YinOYang ∗2, we used the same method to evaluate the performance of YinOYang while the test sets were different. For YinOYang ∗1, the test dataset is the same with that used for phos-based classifier and, for YinOYang ∗2, the test dataset is the same with that used for O-GlcNAc-based classifier.
