High-resolution nucleosome positioning from ATAC-seq chromatin accessibility data

We describe the NucleoATAC algorithm for high-resolution nucleosome positioning and occupancy determination using ATAC-seq. ATAC-seq was performed on Saccharomyces cerevisiae and Schizosaccaromyces pombe. Nucleosomes were called for both species as well as for the human GM12878 cell line using data from GSE47753. Additionally, ATAC-seq was performed on S. cerevisiae undergoing an osmotic stress time-course and nucleosomes were called for each time point.
