Rosetta Develops New Markup Language, Offers it for Free

NEW YORK, Oct 27 – Rosetta Inpharmatics said Friday that it has developed a language for converting various gene expression data files into a common format and that it would distribute it for free along with a package of a new gene expression data visualization tools.

Gene Expression Markup Language, as the company calls the language, is an open-standard XML file format, designed to convert expression data files from various platforms, including Affymetrix GeneChip and BioDiscovery AutoGene into what Rosetta hopes will become a stander format.

“The inability to analyze gene expression data from multiple technology platforms has long been hampered by software compatibility issues,” said Mark Boguski, senior vice president of research and development at Rosetta.

The file converter is part of a suite tools, Rosetta GEML Conductor, designed for visualizing and manipulating data after it is converted to GEML format. The tools include Plot Viewer for zooming in on plot areas created from GEML profiles, Intensity Plot Viewer for measuring the intensity of one data channel against another, as well as hotlinks to popular databases.

Version 1.0 of the freeware can be downloaded from the company’s website.
