Affymetrix: Jan 9, 2007

Affymetrix this week launched the fourth version of its Chromosome Copy Number Analysis Tool.
According to Affy, CNAT 4.0 implements a hidden Markov model algorithm to identify genome-wide chromosomal gains and losses and loss of heterozygosity using its high-density SNP oligonucleotide arrays and its whole-genome sampling assay.
The tool supports all of Affy’s GeneChip mapping array products, including the 500K Mapping Array Set, the company said.
Affy also announced this week that the beta-3 version of its Affymetrix GeneChip Command Console instrument control software is now available for download on its website.
According to the company, AGCC will replace its GeneChip Operating Software and will support all cartridge-based GeneChips with a file-based system designed for easy data sharing, as well as features for sample and array registration, data management, fluidics and scanning instrument control, and automatic and manual image gridding. AGCC will also produce probe cell intensity data, the company said.
An official version is scheduled to launch in June.
