In the search field you can enter any kind of text that exists in the annotation track. As an example, consider the gene and tool tip shown in figure 24.9.
If you wish to locate this gene, any of the following entries could be typed in the search field:
- This would match the annotation name exactly.
- This would match the annotation name as well as other genes with a text starting with BRCA (e.g. the BRCA1 gene).
- This would match the annotation name as well as other genes with a text ending with RCA2 (e.g. the SMARCA2 gene).
- This would match the
db_xrefqualifier for the OMIM database. All the text shown for the annotation in figure 24.9 can be searched this way, both as exact matches and with the * before or after the search term.
The search will be performed throughout the entire genome beginning with the chromosome currently shown and stopping when it finds the first hit. Press Find again to find the next hit. Once the whole genome has been traversed, the status will inform you that you have searched the whole genome. Click the Find button to start the search again.
Please note that you can also use the table view of an annotation track to perform more advanced queries of the data (see Showing a track in a table).
