Figure 4From: Parameter estimation and determinability analysis applied to Drosophila gap gene circuitsRegulatory topology of the gap gene network. Maternal coefficients and regulatory weight matrix for the gap gene system based on parameter sets found by the LM method: a) 64 solutions in the full search case; b) 60 sets in the case of fixed promoter thresholds. Triplets show the number of parameter sets in which a regulatory weight falls into one of the following categories: repression (values ≤ -0.005)/no interaction (values between -0.005 and 0.005)/activation (values ≥ 0.005). Based on the highest value in the triplets, the table is coloured such that the background colours represent activation (green), no interaction (light-blue), or repression (pink).Back to article page
