Rosetta Resolver, Bioperl 0.7


Rosetta Inpharmatics has launched version 2.0 of the Rosetta Resolver enterprise-wide expression data analysis system.

The new version is able to accept and analyze data from single-color, intensity-based DNA chip technologies as well as two-color, ratio-based chips. The system’s error models now compute quality statistics for each intensity measurement and produce P-values for each present/absent call.

Resolver 2.0 also includes a utility that enables automated, batch processing of Affymetrix GeneChip array data files. The system converts, imports, and exports data in the Gene Expression Markup Language (GEML) format.

Version 2.0 is available now through Rosetta’s strategic partner, Agilent Technologies.

The Bioperl 0.7 release is now available at

The release brings a number of new features to bioperl, including an improved sequence feature model and added support in Genbank/ EMBL format parsing. There are also explicit gene, transcript, and exon SeqFeature objects to support CDS retrieval and exon shuffling, new modules for running Blast within perl, and modules for running multiple sequence alignment tools.
