The prevalence of extended nucleosome peaks.

∧The S-I-EtOH-cl1 replicate was more random than the comparable experiments and was excluded from further analyses.
*Peaks in these end-primed experiments are called by Weiner et al.'s (2010) template filtering method.
†In reconstitutions from purified DNA and histones, the highly random protein-influenced positioning frequently makes peak calling uncertain (see Figure S5).
The distributions of peak widths, the numbers of peaks are shown, along with the mean density of uniquely mapping sequencing tags at all peaks. For the abbreviations of experiments, refer to Figure 1.
