Rosetta Inpharmatics, Inc. announced the availability of a new file format, called Gene Expression Markup Language (GEML), to facilitate the interchange of data from DNA chip and other gene expression technologies into a consistent format for more efficient and extensive data analysis. GEML was developed by Rosetta Inpharmatics in an effort to accommodate the growing market need for researchers to have a consistent gene expression data format to use in analyzing data from the growing number of available gene expression technologies. Detailed information on the benefits of GEML and how to use the GEML format is available at GEML is an XML-based data file format that operates independently of any specific database schema. GEML supports data from various gene expression platforms including Affymetrix, Agilent, Incyte, Molecular Dynamics, 1-color or 2-color fluorescent labeling and scanning, nylon filters, and other data formats. GEML also tracks which data format was used, and with this knowledge enables normalization, integration, and comparison of data across technologies. As part of Rosetta’s efforts to encourage this potential industry standard for gene expression data, Rosetta intends to offer users of GEML additional tools for viewing and analysis of genomic data in GEML format. This will enable genomic researchers to publish and analyze data using any tools that support the GEML format. Rosetta intends to pursue future enhancements with input from collaborators in the GEML community, and intends to work with its GEML collaborators to propose this data format as a standard to the Object Management Group (OMG) in November.
