nucleosome_tiling {nucleR} | R Documentation |
Some bases from S.cerevisiae tiling microarray where mononucleosomes were sequenced and hybridizated with histone-free naked DNA. The intensity is the normalized ratio between the intensities from nucleosomic and naked DNA.

Due to the difficulty of providing a raw file, this file has been preprocessed. See details.
The raw .CEL files from Affymetrix S.Cerevisiae Tilling 1.0R Array (3
nucleosomal + 3 naked DNA) has been merged using package Starr
and the
resulting ExpressionSet
object has been passed to processTilingArray
function from this package as follows:
processTilingArray(data, exprName, chrPAttern="Sc:Oct_2003;chr1", closeGaps=50)
The first 8000bp of the chr1 have been saved as this example dataset.
