Cytoband annotation data frame
Description
Cytoband annotation information from the hg19 genome build
Usage
annot.file
Format
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.
Details
The file cytoBand.txt.gz for the hg19 build can be downloaded from the UCSC Genome Browser at
http://hgdownload.cse.ucsc.edu/goldenPath/hg19/database/. The format of cytoBand.txt differs from that
of annot.file, but it can be used by the function makeCytoband if reformat.cytoband = TRUE.
