The performance of the MAPP was assessed using the criteria designed for the EGASP promoter prediction workshop. Each analysis was run with a TP window acceptance size (w) of ± 50 nucleotides or ± 100 nucleotides. t, MAPP score clustering threshold; PPV_w, positive predictive value; Sn_w, sensitivity; F_w, harmonic mean.
