Brick_get_ranges {HiCBricks}R Documentation

Fetch the ranges associated to a rangekey or chromosome.

Description

Brick_get_ranges will get a ranges object if present in the Brick store and return a GRanges object.

Usage

Brick_get_ranges(Brick, chr = NULL, rangekey)

Arguments

Brick

Required. A string specifying the path to the Brick store created with CreateBrick.

chr

Optional. A chr string specifying the chromosome to select from the ranges.

rangekey

Required. A string specifying the name of the ranges.

Details

If a rangekey is present, the ranges will be retrieve and a GRanges constructed. Metadata columns will also be added. If these are rangekeys other than "Bintable", and had been added using Brick_add_ranges the width and Strand columns may appear as metadata columns. These will most likely be artifacts from converting the original ranges object to a data.frame.

Value

Returns a GRanges object with the associated metadata columns that may have been present in the Ranges object.

Examples

Brick.file <- system.file("extdata", "test.hdf", package = "HiCBricks")
Brick_get_ranges(Brick = Brick.file, chr = "chr19", rangekey = "Bintable")
