Expression Pattern Search

Given a cell, a Cell Group, or a Life Stage, you may wonder what kind of genes are expressed there. WormBase Expression Pattern Search provides you the tool to find this out. SELECT SEARCH TERMS First, we need to learn how to select and remove terms. Select from Cell, Cell Group and/or Life Stage, and click the button "Add to search Terms". To select multiple terms from the same category, for example, if you want to choose both "AB.a" and "P12" from Cell, unless those terms are next to each other (use Shift key to select multiple terms in that case), you will have to add them one by one using the "Add to Search Terms" button.

CHANGE RELATIONSHIPS AMONG SEARCH TERMS

In the Query Editor, users can change the relationship among terms. There are four kinds of relationships: AND, OR, AND NOT, OR NOT.

Once the relationship is changed, the search engine will automaticly start the search and list results. Or, if users do not want to change the relationship, clicking the "SEARCH" button will start the search.

WRITE QUERY DIRECTLY

The text box at the bottom of Query Editor shows the Ace Query Language (AQL) the search engine created according to the terms and relationships users selected. Users can also directly write a query in the text box. Please check WormBase Advanced Search for instructions on how to use AQL. Or, go to http://www.acedb.org/Software/whelp/AQL/.
