2DWG Meta Database of 2D Electrophoretic Gel Images

2DWG元数据库是在互联网上找到的2-D电泳凝胶图像的可搜索数据库。元数据库包含有关在其他数据库中定位数据的信息，但不包含数据本身。该数据库的构建是因为需要一组丰富的万维网（Web）位置（URL）的2-D凝胶图像在互联网上。这些凝胶图像与NCI闪烁服务器结合使用，以在互联网上操作和视觉上比较2-D凝胶图像。用户的凝胶也可以与数据库中的凝胶进行比较。2DWG被组织为电子表格，每个凝胶图像由按组织类型排序的行表示。每个凝胶的数据包括组织类型、物种、细胞系、图像URL、数据库URL、凝胶协议、组织URL、图像属性、映射URL（如果存在）等。可以搜索2DWG以找到凝胶的相关子集。使用dbEngine进行搜索-这是一种Web数据库搜索引擎，可访问完整2DWG表中选定的凝胶行。2DWG元数据库可在网站http://www-lecb.ncifcrf.gov/2dwgDB/上访问。

The 2DWG meta-database is a searchable database of 2-D electrophoretic gel images found on the Internet. A meta-database contains information about locating data in other databases - but not that data itself. This database was constructed because of a need for an enriched set of World Wide Web (Web) locations (URLs) of 2-D gel images on the Internet. These gel images are used in conjunction with the NCI Flicker Server to manipulate and visually compare 2-D gel images across the Internet. User's gels may also be compared with those in the database. The 2DWG is organized as a spreadsheet table with each gel image being represented by a row sorted by tissue type. Data for each gel includes tissue type, species, cell-line, image URL, database URL, gel protocol, organization URL, image properties, map URL if it exists, etc. The 2DWG may be searched to find relevant subsets of gels. Searching is done using the dbEngine - a Web database search engine which accesses selected rows of gels from the full 2DWG table. The 2DWG meta-database is accessible on the Web at http://www-lecb.ncifcrf.gov/2dwgDB/.
