The algorithm contains three major parts: 1) Intensity pre-processing using an improved version of Genomic Imbalance Map (GIM) (Ishikawa et al. 2005), including probe selection, noise reduction, normalization, and intensity ratio adjustment based on affinity differences between alleles of a SNP, 2) CNV extraction, which identifies CNVs from all pair-wise comparisons using a modified SW-ARRAY, and 3) A copy number inference step which utilizes signal ratios and SNP information to more precisely define CNV boundaries and the copy number within each region. | | Platform | Affymetrix GeneChip Early Access Mapping 500K Set Array (250K_Nsp_SNP) | | Comments | | | Reference | Redon_et_al_2006 | | Pubmed ID | 17122850 | | Accession Number(s) | esv2759010
