## aCGH / Add cytogenetic bands

### Description

Adds the cytogenetic band information using chromosome names and start/end base pair positions. If this position information is not present in your data set, please first run the Fetch probe positions from CanGEM tool.

### Parameters

- Human genome build to use (GRCh37/hg19, NCBI36/hg18, NCBI35/hg17, NCBI34/hg16) [GRCh37/hg19]

### Details

The locations of the cytogenetic bands in different builds of the human genome have been obtained from the Ensembl database using the MySQL commands listed on this page.

### Output

The input file appended with a new column (cytoband) containing the name of the cytogenetic band (e.g. "8q24.21"). If the start and end positions are contained within different cytogenetic bands, the two bands are separated with a hyphen (e.g. "8q22.1-8q24.3").
