Before revision:  As an application of our methods , we analyze the large-scale regulatory network of E. colinumerically: We identify the most determinative nodes and show that a small set of those reduces the overall uncertainty of network states significantly. The network is also found to be tolerant to perturbations of its inputs , which can be seen from the Fourier spectrum of its functions .
