Description Genomic DNA extracted from breast tumors was was interrogated for copy number against pooled normal genomic DNA on the Agilent Human Genome CGH Microarray Kit 244A.
Data processing Data were processed from raw text files using R and limma (using limma's “agilent” source option). Probes apparently not 60 bases in length were removed and arrays were normalized using the normexp deconvolution background correction method and loess regression of log-ratios to remove dye-bias.
