In trena: Fit transcriptional regulatory networks using gene expression, priors, machine learning

Description

Get a table of regulatory regions for a Human DHS filter

Usage

## S4 method for signature 'HumanDHSFilter'
getRegulatoryRegions(
  obj,
  encode.table.name,
  chromosome,
  start,
  end,
  score.threshold = 0
)

Arguments

obj	An object of class HumanDHSFilter
encode.table.name	A vector of names for Encode tables
chromosome	The chromosome of interest
start	The starting position
end	The ending position
score.threshold	A threshold for the score (default = 200)

Value

A data frame containing the regulatory regions for the filter, including the chromosome, start, and end positions, plus the count and score of each region.
