## aCGH Agilent Probes GC Fraction

### Description

A dataset containing the Agilent probe Ids, and their GC content.
These data allow `rCGH` to support Agilent aCGH arrays, from 44K to 400K. See the `source` section.
This information is used to correct the GC% bias. For Agilent data only.

### Usage

    agilentDB

### Format

A data frame with 411056 rows and 2 columns:

- ProbeID: Official Agilent probe ids.

- GC: The GC content in each probe sequence, expressed as the GC fraction.

### Value

A dataset

### Note

Probe sequences are not used and have been removed after computing the GC fractions as GC = sum(G or C)/length(sequence), for each sequence in file.
