Silicon Genetics has released GeneSpring 7 and Signet 5. Enhancements in GeneSpring 7 include new support vector machines, project-based organization, a new Genome Wizard for genome import and management, and a Java API. Signet 5 (formerly called GeNet) now includes a SOAP API, a native Java plug-in API, project-based navigation, and modifiable workspaces.
Version 2.0 of Cytoscape is available at http://www.cytoscape.org. Cytoscape visualizes molecular interaction networks and integrates those interactions with gene expression profiles and other data. New features include the ability to load and save networks in SIF and GML formats, a new open-source graph library, and a new programmer API. Cytoscape is jointly developed by researchers at the Pasteur Institute, the University of California, San Diego, Memorial Sloan-Kettering Cancer Center, and the Institute of Systems Biology.
OpenEye Scientific Software has released Omega 1.8, a software package that generates multi-conformer structure databases for computer-aided drug design. New features include a new distance-bounds method to get better starting structures, and improved ring templates.
Inte:Ligand has launched a new virtual library generation package called ilib diverse. The software builds compounds by combining user-defined fragments. User-adjustable constraints allow a combinatorial approach that provides good structural diversity and fast, automated lead structure modification, according to the company.
