    • The property of η*(q)=η(-q) is needed to guarantee that the inverse Fourier transform gives a sequence of real numbers. Equation ( refdelta) can be derived from this criterion.

    • This is not the only way to generate correlated variables, but the algorithm of Eq. ( refuq) has two advantages: (i) For β=0, we obtain Gaussian white noise. (ii) For β=2, we obtain Brown noise (a representation of Brownian motion).

    • The definition of αlocal will affect its fluctuations. In this study, we measure the slopes of successive pairs of data points that are uniformly distributed on a logarithmic scale of ell. To be more precise, we define αlocal( elli,N) =[ log10 F( elli+1) - log10 F( elli)]/ ( log10 elli+1 - log10 elli), where elli is the integer part of 2i/2) and i=0,1,2,3, ldots. This same definition of αlocal has been used by many authors in the context of calculating critical point exponents; the analog of Fig. 2 was constructed for a range of genes first by A. A. Tsonis, J. B. Elsner, and P. A. Tsonis (unpublished), and by S. V. Buldyrev, A. L. Goldberger, S. Havlin, C. K. Peng, M. Simons, and H. E. Stanley, Phys. Rev. E (to be published).

    • We have also checked 34 different sequences (including sequences of length ranging from 3000 to 300,000 nucleotides) and found that the fluctuations in the successive slopes αlocal are comparable to the fluctuations in the artificial sequence.

    • For the analogous problem of studying fluctuations in exponent α in d dimensional systems due to finite size effects, we expect that Δαlocal( ell,N) sim ( ell/N)d/2. For a fractal system, d should be replaced by df, the fractal dimension of the system.
