Performance comparison of NT-AcPredictor with other predictors

	TPR	SPC	PPV	ACC	MCC	F1
NT-AcPredictor	0.858	0.815	0.830	0.837	0.674	0.844
NetAcet	0.384	0.947	0.929	0.587	0.361	0.544
Motifs tree	0.929	0.845	0.863	0.888	0.778	0.895

TPR, SPC, PPV, ACC, MCC, and F1 represent true positive rate, specificity, positive prediction value, accuracy, Matthews correlation coefficient, and F1 score, respectively. Note that NetAcet was unable to output prediction result for 73 proteins because the predictor did not output the results when the input sequences did not include Ala, Gly, Ser, or Thr at the position from 2 to 4
