The UCSC Table Browser is a text-based data retrieval tool that provides access to a comprehensive collection of genome assemblies and annotation data stored in the Genome Browser Database. This tool offers enhanced query capabilities, including field value restrictions, free-form SQL queries, and combined queries across multiple tables. Users can filter and organize output in various formats, such as tab-delimited files or custom annotation tracks for the Genome Browser. The Table Browser supports positional and non-positional tables, with optimizations for efficient data retrieval and interactive performance. Advanced features include filtering, multiple table comparisons, and subregion retrieval. Future developments aim to add batch query processing and simultaneous data retrieval from multiple positions. The tool is accessible via the UCSC website and is supported by a mailing list for user feedback and discussions.The UCSC Table Browser is a text-based data retrieval tool that provides access to a comprehensive collection of genome assemblies and annotation data stored in the Genome Browser Database.
