The 2DWG Meta-Database of 2-D Electrophoretic Gel Images

2DWG元数据库是在互联网上发现的二维电泳凝胶图像的可搜索数据库。元数据库包含关于在其他数据库中定位数据的信息——但不包含数据本身。该数据库的建立是由于需要在互联网上丰富的二维凝胶图像的万维网位置（url）集。这些凝胶图像与NCI闪烁服务器一起使用，以操纵和直观地比较互联网上的二维凝胶图像。用户的凝胶也可以与数据库中的凝胶进行比较。2DWG被组织成一个电子表格，每个凝胶图像由按组织类型排序的一行表示。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、地图URL（如果存在的话）等。可以搜索2DWG以找到相关的凝胶子集。搜索是使用dbEngine完成的——dbEngine是一个Web数据库搜索引擎，它从完整的2DWG表中访问选定的凝胶行。2DWG元数据库可在Web上访问，网址为http://www-lecb.ncifcrf.gov/2dwgDB/。

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/.
