Field: NMR-STAR 3.1 tag or tags (fields) to search. Click on the icon to see the tag definition in the NMR-STAR dictionary.
Value to search for: you can use POSIX regular expressions supported by PostgreSQL database engine (see the link for details). For a quick example, when searching for Entry ID:
|.||list of all BMRB IDs in the database (dot stands for "any character")|
|15.*||list of BMRB IDs with "15" anywhere in the number (asterisk stands for "zero or more of the preceding character")|
|^15.$||list of BMRB IDs between 150 and 159 (caret and dollar sign stand for start and end of the match resp.)|
|^15[0-3]$||list of BMRB IDs between 150 and 153 (ranges are specified in square brackets)|
|^15(0|6)$||BMRB IDs 150 and 156 (use vertical pipe for "or" and parentheses for grouping)|
Display checkbox: select the fields to include in the output.
Output: you can select whether to render the output as an HTML table, or a comma-delimited table suitable for importing into spreadsheet programs. If you'd like to see the CSV table in the browser, and your browser opens the "Save As" dialog (or fires up a spreadsheet opens the table in that) instead, tick the "inline" checkbox.
Note that there is a small number of BMRB entries that have not been converted to NMR-STAR 3.1 yet. They are not loaded into the NMR-STAR 3.1 relational database and so the search will not find them. BMRB entries available only in NMR-STAR 2.1 format.
