ODE files for mutually activating and mutually inhibiting network motifs
The .ode files can be run using freely available software XPPAut (http://www.math.pitt.edu/~bard/xpp/xpp.html) to generate the phase planes of Figs. 1D and 1E.
For Figs. 2A, 2B, and 2C, the cyclin B total is varied by changing the parameter Xt. For Fig. 2B, set parameters kay2=0 and kay=0.005.
