get.chrom.length: Get Chromosome Length

In GRIN2: Genomic Random Interval (GRIN)

Get Chromosome Length

Description

Retrieves chromosome size data for the 22 autosomes and X and Y chromosomes of the human GRCh38 (hg38) genome assembly using UCSC chromosome information accessed through the circlize package.

Usage

get.chrom.length(genome.assembly)

Arguments

genome.assembly

Character string specifying the genome assembly. Currently, only "Human_GRCh38" is supported.

Details

The function retrieves chromosome size information for the GRCh38 (hg38) genome assembly using circlize::read.chromInfo(). The returned data are restricted to the 22 autosomes and X and Y chromosomes and are ordered from chromosome 1 through chromosome 22, followed by X and Y. Chromosome identifiers are returned without the "chr" prefix.

Value

A data.frame with 24 rows and the following columns:

chrom

Chromosome identifier (1-22, X, or Y).

size

Chromosome size in base pairs.
