Read chromatin domain bed file

Description

This dataExample object comprises three objects: GenomicFeatureList.GR, AnnotNames and Domains.GR. GenomicFeatureList.GR is a list of GRanges objects, one for each genomic feature to analyze. AnnotNames is a vector of the genomic feature names. Domains.GR is a GRanges object for topologically associating domains.

Topologically associating domains (object Domains.GR) were computed from Hi-C experiments on Drosophila melanogaster Kc167 cells from Gene Expression Omnibus (GEO) accession GSE62904. ChIP-seq data (object GenomicFeatureList.GR) on Drosophila melanogaster Kc167 cells were downloaded from Gene Expression Omnibus (GEO) accessions GSE30740, GSE42085 and GSE54529. Only data for chromosome 2L are provided.
