Dynamical behaviour of the E. coli TRN for a fixed environment, glucose aerobic minimal media. For all initial conditions the system is attracted to a fixed point whose configuration depends upon the medium. The plots depict, as a function of time, the hamming distance of the configuration from the fixed point attractor corresponding to the medium. 4 different initial conditions are shown. One is a randomly chosen initial condition. Another is the 'hamming inverse' of the attractor (in which the configuration of every gene is reversed with respect to the attractor). Two other initial conditions are the attractor configurations of other minimal media.
