Annotations editor

Annotation editor contains tools to manipulate annotations for a sequence. It provides a convenient way to organize, view and modify single annotations as well as annotation groups.

The annotation for a sequence consists of

Annotation editor explained


Annotation groups are used by UGENE for logical organization of annotations. Each of annotations always belongs to some group.

For documents created not by UGENE annotations are grouped by their names. For annotations created in UGENE it's possible to use arbitrary group names.

Groups can contain both annotations and other groups. The numbers in the brackets after a group name in Annotation editor are the count of sub-groups and annotations in the current group.

A single annotation is allowed to present in multiple groups simultanously. An annoation is phisically removed from the document when it does not belong to any group.



Creating, saving and editing annotations

To create new annotation for the active sequence press Ctrl-N key sequence or use "Add->New Annotation" context menu:

Creating new annotation


This will activate a dialog where to set up annotation parameters:

A dialog to create new annotation


The dialog asks where to save the annotation. It could be either an existing annotation table object or a new document(file).

You can also specify the name of the group and the name of the annotation. If group name is set to <auto> UGENE will use the annotation name as the name for the group. You can use '/' characters in this field as a group name separator to create subgroups.

The 'Location' field contains annotation coordinates. The coordinates must be provided in Plain Genbank or EMBL file formats. If you want to annotate complement sequence strand surround the coordinates with 'complement()' word or press the last button in the 'Location' row to do it automatically.

Note, that by default 'Location' field contains the coordinates for the selected sequence region.

Once the 'Create' button is pressed the annotation is created and highlighted both in Sequence overview and Sequence details widgets:

The result


To add qualifiers to the newly created annotation select the annotation in Annotation editor and press Insert button or use "Add->Qualifier" context menu:

Adding qualifiers


To rename annotation or annotation group use F2 button.

Selected annotations, groups and qualifiers can be deleted with Delete button.

To remove an annotation object from the active view, select the object in Annotation editor and press Shift-Delete. Note that the object will not be removed from the project, but just from the active Sequence view.

To add object again just drag and drop it to a Sequence view.
