You can add annotations to a sequence by searching the feature library. Search is strand-specific and is done by feature’s sequence with an exact match approach but case insensitive.

In the sequence tab that you want to add feature annotations, press “ACTIONS” -> “Detect Features”. The system will search for features from the library in the current sequence.

• If the feature library is empty, the Detect Feature option will not be available.
• If the current sequence doesn’t contain any of the features' sequence from the library, there will be a notification “No featured from the library were found in the sequence” on the screen.
• If the current sequence contains some features' sequences from the library, you will be able to review the list of detected features. Clicking the down arrow next to each feature will expand the feature to show feature properties: such as name, type, location in the sequence (start, end, strand), and other properties available in the library. All detected features are selected by default. If there is a feature you don’t want to add to the current sequence, you can remove the checkmark in front of it. Pressing the “ADD” button will add all selected features to the annotation of the current sequence. These features are displayed on the scene and are added to the feature list.
• When searching for features in the RNA sequence, the system treats all “T” bases in the feature sequence as “U”.
