Lion Bioscience, Heidelberg, Germany, has launched its arrayTag and arrayBase tools for rat gene expression data analysis.

ArrayTag is a non-redundant set of 10,000 cDNA clones for rat and is linked to the arrayBase annotation database, which provides information about each clone. The tools complement Lion’s arrayTag and arrayBase collection for the mouse, which was launched in January.

Lion plans to offer more non-redundant sets of arrayTag for mouse and rat, as well as for other animal species that are widely used as model organisms in biomedical research.

The Theoretical Biophysics Group at the University of Illinois has released a new version of NAMD, a parallel, object-oriented molecular dynamics code designed for high-performance simulation of large biomolecular systems.

NAMD is distributed free of charge and includes source code. NAMD 2.3b1 includes a new psfgen tool for building PSF structure files and new ports to the Compaq AlphaServer SC and Scyld Beowulf.

NAMD development is supported by the NIH National Center for Research Resources.

The code is available at www.ks.uiuc.edu/Research/namd.
