annot.file: A Cytoband Annotation Data Frame

Description

This four-column data frame contains cytoband annotation data that is used by the makeCytoband function. Each row corresponds to a distinct cytoband, and column 1 contains the chromosome number, column 2 contains the start position (in base pairs), column 3 contains the end position (in base pairs), and column 4 contains the cytoband name (e.g. p21.3). Additional columns may be present, but they are not used.

Usage

data(annot.file)

Format

A data frame with 811 observations on the following 4 variables.

Chr

The chromosome for the cytoband

Start

The start position (in base pairs) for the cytoband

End

The end position (in base pairs) for the cytoband

Band

The cytoband name (e.g. p13.1)
