    • Although the data for polyamide 2 (Figure 6a) maps intensity and Ka values using the linearized equation 2, this fit is distinct from that obtained by fitting the data to a line of the form y, mx, b, which includes an intensity-axis intercept term. While very small in this case, the differences in the slopes and intercepts of the lines may indicate error both in the background correction of the microarray and in the DNase I footprinting data. To correct for this possibility, we propose the use of an error term, ε, that would modify eqs 1 and 2 to the following: Intensity, c × Θ, ε, c x {K a[PA], 1, Ka[PA, ε, c x, PA], Kd, PA, ε (eq 1e) and Intensity, c x [PA]/Kd, ε, c x [PA] x Ka, ε eq 2e, When fitting the intensity and Ka data for polyamide 2

    • Figure 8 utilized 10 variable bases and contained a background GC content of 50%; Figure 9 utilized 10 variable bases and two fixed bases, each flanking the 5′ and 3′ portion of the variable region, and contained a background GC content of 58%. These background GC content corrections were utilized in the motif searching parameters.
