GRangesList contains a subset of drosophila
melanogaster ChIP-sequencing data
obtained with the Illumina sequencer.
An immuno-precipitated and a control input sample were obtained at two
experimental dates (details not provided as this is still unpublished data).
In order to save space and let the examples run quicker,
only reads mapping to the first 500kb of chr2L are included.
GRangesList where each element contains reads from a
names(htSample) indicate the group and batch (experimental
date) that each sample corresponds to.
Data was pre-processed using the Illumina pipeline and mapped to the drosophila melanogaster dm3 genome using Bowtie. Only uniquely mapping sequences with at most 2 mismatches in the first 28 bases were kept. See the package vignette for some more details on this dataset.
