cutoff α. A. Distribution of co-occurring scores S
of the motif pairs found in the 16 datasets. The curve is a fitting of the left portion of the distribution to a Gaussian distribution N(μ = 0.19, σ = 0.067). B. The remaining proportions of predicted motifs and known CRMs as functions of the S
cutoff α. The vertical line indicates the position of the chosen cutoff α = 0.7 for selecting co-occurring motif pairs (CPs).
