From the Broad Institute--a research alliance of Harvard University, the Whitehead Institute for Biomedical Research, and the Massachusetts Institute of Technology--this website makes a variety of genomic resources publicly available to researchers. The site links to Genome Sequence Databases under the following categories: Fungal, Vertebrate Lineage, Bacterium, Mammalian, and Archaebacterium. Examples of software available through the site include Locusview 2.0: A Program for Generating Images of Chromosomal Regions; GeneCruiser: Annotation for Microarray Data; Radiation Hybrid Mapping; and GeneCluster2: An Advanced Gene Expression Analysis Toolkit. The site also links to publications from different research groups such as the Neuropsychiatric Genetics Group, Population Genetics Group, Inflammatory Disease Research Group, and Computational Biology & Bioinformatics Group. Mapping Project Links are available as well.
