Receiver Operator Characteristic plots evaluating how well the npFis and pFis motifs from Figure 6 and the previously established Fis motif (Hengen et al. 1997) discriminated all (log ratio ≥ 1) Fis-peak-associated chromosomal sequences from random chromosomal sequences. The plotted curves are the average of 20 discrimination experiments that used different random chromosomal sequence sets.
