The VARNA RNA Viewer
-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).
+
+ 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

-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.
