Rawcopy: Improved copy number analysis with Affymetrix arrays

Microarray data is subject to noise and systematic variation that negatively affects the resolution of copy number analysis. We describe Rawcopy, an R package for processing of Affymetrix CytoScan HD, CytoScan 750k and SNP 6.0 microarray raw intensities (CEL files). Noise characteristics of a large number of reference samples are used to estimate log ratio and B-allele frequency for total and a...

ITALICS: an algorithm for normalization and DNA copy number calling for Affymetrix SNP arrays

MOTIVATION Affymetrix SNP arrays can be used to determine the DNA copy number measurement of 11 000-500 000 SNPs along the genome. Their high density facilitates the precise localization of genomic alterations and makes them a powerful tool for studies of cancers and copy number polymorphism. Like other microarray technologies it is influenced by non-relevant sources of variation, requiring cor...

Analysis of Affymetrix Exon Arrays

Exon arrays enable the monitoring of expression on a more fine-grained level than conventional 3' arrays. By targeting single exons alternative splicing events can be detected. However, the increased amount of data resulting from the denser coverage of the transcribed regions gives rise to new challenges in data analysis compared to 3' arrays. One must carefully decide which probes are consider...

The Analysis of Biases of Copy Numbers from Affymetrix Snp Arrays

Affymetrix SNP arrays are widely used for both genome-wide association and copy number variation (CNV) studies, both of which depend on accurate copy number estimation. However, depending on the method used to copy number estimation, distortions from the actual copy numbers can occur. Therefore, we demonstrate here several effects that can bias accurate copy number estimation, and we describe h...

High-Resolution Chromosome Copy Number Analysis Using GeneChip Mapping Arrays

Chromosome copy number analysis using whole-genome expression and genotyping microarray technology is fundamentally improving our understanding of human disease. The GeneChip Human Mapping 100K Set in combination with the GeneChip Chromosome Copy Number Analysis Tool enables researchers to detect copy number alterations, loss of heterozygosity (LOH), and genotypes in a single experiment. High-r...
