Abstract

Nucleosomes have position-specific functions in controlling gene expression. A complete systematic genome-wide reference map of absolute and relative nucleosome positions is needed to minimize potential confusion when referring to the function of individual nucleosomes (or nucleosome-free regions) across datasets. We compiled six high-resolution genome-wide maps of Saccharomyces cerevisiae nucleosome positions from multiple labs and detection platforms, and report new insights. Data downloads, reference position assignment software, queries, and a visualization browser are available online http://atlas.bx.psu.edu/ webcite.
