## Centromere base positions

### Description

Centromere base positions from the GRCh36/hg18, GRCh37/hg19 and GRCh38/hg38 genome builds.

### Usage

    data(centromeres.hg18)
    data(centromeres.hg19)
    data(centromeres.hg38)

### Format

A data frame with the following columns.

`chrom`

  chromosome (1-22, X, Y)

`left.base`

  starting base position of centromere

`right.base`

  ending base position of centromere

### Note

The UCSC genome browser lists two regions for the Y chromosome centromere in build hg18. We removed the positions (12208578, 12308578) from the centromere table to avoid problems with duplicate entries in the code.
