Data processing: Probe-level signal intensities were normalized to a common reference array using quantile normalization and combined to form SNP-level signal intensities using the dChip model-based expression (PM/MM) method . Genome-wide copy number estimates were obtained using tangent normalization, in which tumor signal intensities are divided by signal intensities from the linear combination of all normal samples that is most similar to the tumor (as described in Beroukhim et al, In Press; and Getz et al., In Preparation). Cancer samples were normalized against a pool of 1,480 reference samples derived from multiple studies; the code and reference data necessary to replicate this analysis are available for download in GEO. Genotype Call (SNP call) are provided in .CHP.TXT files: AA, AB, BB, NC, and NoCall.
