The VARNA RNA Viewer

Since Jalview -2.7.1, VARNA has been -integrated into Jalview for interactively viewing structures opened by -selecting the "Structure→View -Structure:" option in -the sequence id pop-up menu (if -you can't see this, then no RNA structure is associated with your -sequence or alignment. In the pop-up menu all structures that -are associated with this sequence and all sequences that are -associated with the alignment are available. - -

Different structures

- Alignment structures: - Structures associated with the alignment are marked by having "consensus" attached to their name. VARNA contains two different entries for consensus structures. -
- Consensus structure: the individual sequence folded into the consensus structure
- Trimmed consensus structure: the individual sequence - folded into the the gap-free consensus structure. That means all - columns that contained gaps in the individual sequence were - removed. If this breaks a base-pair the pairing is removed also. - This can be considered as an approximation for the individual structure. -
-
- Individual structures: - this is a structure associated with the individual sequence and therefore not related to the alignment -

Controls
-

Rotate view - Left Click and drag
Zoom in - Press '+'
Zoom out - Press '-'
Choose a different structure - Left click on structure in the left hand panel
Highlighting bases - Move mouse over columns in the Jalview alignment panel

Functionality provided by VARNA

VARNA's own functions are accessed by right-clicking in the -structure display area. That will open the VARNA pop-up menu, -which provides access to a number of features like different draw algorithm, color highlighting or annotations. -

More Information

VARNA is a very powerful RNA viewer on its own. Only the -essentials have been described here - the interested reader is -referred to VARNA's own -comprehensive online documentation.

+ The VARNA RNA Viewer +

+ VARNA was integrated + into Jalview 2.8 to allow interactive viewing of RNA secondary + structure annotation. It is opened by selecting the "Structure→View + Structure:" option in the sequence + id pop-up menu (if you can't see this, then no RNA structure is + associated with your sequence or alignment). In the pop-up menu all + structures that are associated with this sequence and all sequences + that are associated with the alignment are available. +

+ Saving a Jalview session as a project file includes the state of any + Varna viewers, which are reopened when the project is reloaded (since + Jalview 2.9). +
