Fig 4. SPSD for the cases of the D and the DO perturbations.

The SPSD of the 3-variable Boolean function T = RF₁•RF₂•RF₃ is depicted for two types of perturbations experiments. A: Only knock-down is employed as the perturbation. Only edges labeled by D_i exist in the SPSD. B: Both knock-down and over-expression perturbations are used.
