The LBL/UCSF Resource for Molecular Cytogenetics has been created to facilitate the application of molecular cytogenetics in clinical and biological studies. Work is being pursued in three areas: Development and application of improved hybridization technology, selection of probes optimized for use in fluorescence in situ hybridization (FISH) and development of digital imaging microscopy. All of these areas entail creation and manipulation of large images and other laboratory data. Our group is focussed to provide data management support for all the activities in the Resource.
To facilitate the free data exchange between researchers at UCSF and LBL which are a few miles apart we developed a Mosaic interface to access and modify information using the World Wide Web. The data are located-on a central database. The Mosaic client allows to formulate retrieval and edit operations that are sent to the database. Results are filtered through a Perl script which generates HTML documents with Hypertext links that are sent back to the Mosaic client. Data from the Resource are made available using a similar mechanism that is open to outside access.
Probe information and mapping data from the Resource are being submitted to public databases, i.e., GDB. In a collaboration with GDB we have developed a data submission tool (see separate abstract by Manfred Zorn) to facilitate the distribution of our research results.
In order to handle large amounts of images we are developing an image annotation database. The images themselves are automatically transferred to the LBL Mass Storage System. The annotation will be reformatted and loaded into a relational database to allow efficient query processing.
We will present an overview and the current status of our work.
