Finding annotations on the genome

In the Side Panel under Find, a search field allows you to quickly find the annotation that you are looking for. The list of tracks further allows you to restrict the search to a particular track (e.g. a gene track).

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 24.11.

This gene could be found by searching for the name specifically or, by using a wildcards (asterisks), less specific search terms could be use, giving more flexibility. To find BRCA2, for example, any of the following entries could be typed in the search field:

Just below the search field in the Side Panel, a status label informs about the progress of the search and the hit that has been found. Placing the mouse on top of the label will display a tooltip with more info (see 24.12).

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. When clicking on the annotation of interest in the table, the track list will zoom to that annotation.

Hovering the mouse cursor over an annotation in the track will display (figure 24.13):
