Chip type: CytoScanHD_Array
From Affymetrix' web site: "The CytoScan HD Solution provides the broadest coverage, highest performance, and most "genotype-able" single nucleotide polymorphisms (SNPs) for detecting human chromosomal aberrations associated with genes related to constitutional and cancer cytogenetics, OMIM, and RefSeq. This single array includes more than 2.6 million copy number markers of which 750,000 are "genotype-able" SNPs and 1.9 million are non-polymorphic probes." (Released approx July 2011).
