Natrajan et al. (J. Pathology (2006) 210: 49 - 58) used array comparative genomic hybridization to obtain genome-wide DNA copy number data from 97 Wilms' tumor samples at 3288 markers. This matrix contains the DNA copy number data after applying the bias-correction procedure outlined in Bioinformatics (2011) 27(5) 678 - 685. Each row corresponds to DNA copy number from one subject at 3288 markers, while each column contains DNA copy number data for 97 subjects at one marker.
