Boolean Anatomy Search

1. To find components in the anatomy tree, expand the tree or type all or part of the name of the component/structure you wish to find in the ‘Find components in tree’ text box.   TS = Theiler Stage.

2. Click on a component in the tree to add it to the Boolean Search (3.). The example shown here is using 'testis'. The selected component appears in red in the right-hand section (3.). To correct a mistake, click again on the component: this will remove it from the search.
The same component may appear at different locations in the anatomy tree depending on developmental stage, e.g. renal vesicle (TS20-21) and renal vesicle (TS22-27). The stage range is disregarded when selecting a component for the Boolean Search, for example both renal vesicle (TS20-21) and renal vesicle (TS22-27) will just give 'renal vesicle' as the search term. The Theiler Stage range is then set separately in the editable parameter in the right-hand section (3.).

3. Up to 3 components can be incorporated into an advanced query. Use the pull-down menus and click-boxes to select the desired stage range, expression, pattern and location (Checking 2 boxes for expression will search for e.g. present OR uncertain). You can then repeat steps 1 - 3 to added in a second or third component to the query.
The interactive query builder allows you to build queries with up to 3 terms. In queries with 3 terms (2 operators), precedence is given to the first Boolean operator.
Example 1: A AND B OR C = (A AND B) OR C.
Example 2: A OR B AND C = (A OR B) AND C.

The built query is shown at the bottom of the page (4.). This can be modified or extended using the same syntax (see help).

4. Click 'Run Query' to execute query or 'Save Query' to save. Queries with more than 3 terms can be built in text form in the text box at the foot of the Boolean Anatomy Search page using the Boolean Search Syntax. The Boolean Search Syntax Help Page gives a guide to using this syntax. In queries with more than 2 terms, precedence is given to the first operator and all other operators are treated independently.
The query searches for either genes or GUDMAP entries. Use the pull-down selection menu at the top of the right-hand panel (3.) to choose between the two.
