## S4 method for signature 'FootprintFinder'
getGenePromoterRegion(
  obj,
  gene,
  size.upstream = 1000,
  size.downstream = 0,
  biotype = "protein_coding",
  moleculetype = "gene"
)

Arguments

obj

An object of class FootprintFinder

gene

A gene name of ID

size.upstream

An integer denoting the distance upstream of the target gene to look for footprints (default = 1000)

size.downstream

An integer denoting the distance downstream of the target gene to look for footprints (default = 0)

biotype

A type of biological unit (default="protein_coding")

moleculetype

A type of molecule (default="gene")

Value

A list containing 3 elements: 1) chr : The name of the chromosome containing the promoter region for the specified gene 2) start : The starting location of the promoter region for the specified gene 3) end : The ending location of the promoter region for the specified gene
