Program name	NNPP (threshold 0.8)	Soft Berry (TSSW)	Promoter Scan version 1.7	Dragon Promoter Finder version 1.4	Promoter 2.0 Prediction Server	Prometheus
Sensitivity (%)a	32	60	40	38	50	86
Specificity (%)b	34	65	56	64	54	88
Correlation coefficientc	0.34	0.27	0.11	0.18	0.20	0.74

^aSensitivity = 100 × TP/(TP + FN).

^bSpecificity = 100 × TN/(TN + FP).

^c$\text{Correlation coefficient}\left(\text{CC}\right)=\frac{\left(\text{TP}\times \text{TN}\right)-\left(\text{FN}\times \text{FP}\right)}{\sqrt{\left(\text{TP}+\text{FN}\right)\times (\text{TN}+\text{FP})\times \left(\text{TP}+\text{FP}\right)\times \left(\text{TN}+\text{FN}\right)}}.$
