NEW YORK (GenomeWeb News) - Genedata said today that its Expressionist biomarker-discovery software has gained Affymetrix GeneChip-compatible status for exon expression applications.
A company spokesman said that Expressionist was previously compatible only with Affy’s expression arrays. He said that expanding support to exon expression analysis required file format changes as well as additional “data hierarchy” capabilities because each gene may have multiple exons that each have multiple probes.
In addition, he said that data volumes for the exon arrays are larger than expression arrays, because they contain 1.4 million probe sets instead of 500,000.
Expressionist includes a Refiner Array module for quality assessment and processing of GeneChip exon data, Genedata said.
