relateChers: Relate found Chers to genomic features

Description

This function relates found 'cher's (ChIP-enriched regions) to annotated genomic features, such as transcripts.

Usage

relateChers(pl, gff, upstream = 5000, verbose = TRUE)

Arguments

pl
Object of class cherList
gff
data.frame holding genomic feature annotation
upstream
up to how many bases upstream of annotated genomic features should chers be counted as related to that feature (see details)
verbose
logical; extended output to STDOUT?

Value

An object of class cherList with for each cher the elements typeUpstream and typeInside filled in with the names of the features that have been related to.

Details

chers will be counted as related to genomic features, if
  • their middle position is located between start and end position of the feature
  • their middle position is located not more than argument upstream bases upstream of the feature start
. One can visualize such cher-feature relations as a graph using the Bioconductor package Rgraphviz. See the script 'graphChers2Transcripts.R' in Ringo's scripts directory for an example.
