In SVM2CRM: SVM2CRM: support vector machine for cis-regulatory elements detections

Description

Find the overlap of genomic regions between the output of cisREfind and a database of validated cis-regulatory elements.

Usage

    findFeatureOverlap(query, subject, select)

Arguments

query	database of validatated cis-regulatory elements (e.g. p300 binding sites), GRanges class.
subject	output cisREfindbed function, GRanges class.
select	parameters of findOverlaps

Details

See documentation of GenomicRanges for details.

Value

A data frame with the genomic regions that overlap
