Data files for Whitehouse et al., 2007
Note about nucleosomes:
Nucleosomes are called by iteratively fitting an idealized nucleosome signal to the data. Signals with the best fit are designated as positioned nucleosomes. Bear in mind that this technique will generally NOT detect highly delocalized (fuzzy) nucleosomes. Please do not interpret regions without positioned nucleosomes as being nucleosome free!
