Links between datasets When a user accesses a gene from any dataset on the website, a gene page is displayed that provides links to all T1DBase datasets that contain the gene. From this page, the user can also get to GBrowse and most other tools that can manipulate the gene. In addition, the gene page includes links to the following external resources: LocusLink, UniGene, HomoloGene, OMIM, GeneCards and EPConDB. We are in the process of developing similar links within the major tools on the site, so that tools can use information from any dataset to modify how data are visualized or processed.
