Figure 2. Goodness-of-fit matrices for the 1,619 filtered TFs in the transcriptional network.

Each element (i, j) of a matrix indicates the goodness-of-fit, measured by the coefficient of determination r², by the depth of the colour. Red indicates b_ij > 0, where b_ij is the slope coefficient¹³ between the temporal expression profiles of i-th and j-th TF, suggesting promotive regulation; blue indicates b_ij < 0, suggesting inhibitory regulation. Letters on the dendrograms indicate the branch from which the TFs in the corresponding cluster split off. The heat-maps (right and below the matrices) show the temporal expression profiles of the TFs.
