Basic Chromosomal Information for UCSC Human Genome Assembly July 2003 freeze

Description

This dataset contains basic chromosomal information for UCSC Human Genome Assembly July 2003 freeze. human.chrom.info.Jul03 is loaded automatically with the aCGH package.

Usage

human.chrom.info.Jul03

Format

A data frame with 24 observations on the following 3 variables.

chrom

Chromosomal index, X is coded as 23 and Y as 24.

length

Length of each chromosome in kilobases.

centromere

Location of the centromere on the chromosome (kb).

Details

This file is used for many plotting functions and needs to correspond to clones.info mapping file. The centromeric location is approximately extimated by taking mid-point between the last fish-mapped clone on the p-arm and the first fish-mapped clone on the q-arm using relevant UCSC freeze. For an alternative freeze, one needs to manually create a 3-column file of the format described above.
