- Sequence Feature - Settings for the Jalview Application
Sequence Feature Settings Dialog Box
-Select View→Feature Settings... menu entry in -an alignment window to open the feature settings dialog box, which -allows you to precisely control the presence and appearance of -sequence features for the current alignment.
- The top section of the dialog box lists all the sequence feature - groups, along with a tickbox for each that controls whether its - features are displayed. The table in the middle lists all the - features in the currently selected groups, along with their display - colour and whether they are currently being displayed (only the - ticked features and groups are displayed). You can change the - colour used for a feature in the associated alignment by clicking on - its colour box.
-Transparency and Feature Ordering
- It is important to realise that sequence features are often not - distinct and often overlap (for example, a metal binding site - feature may be attached to one position along a stretch of sequence - marked with a secondary structure feature).
-The ordering of the sequence features in the dialog box list is the
- order used by jalview for rendering sequence features. A feature at
- the bottom of the list is rendered below a feature higher
- up in the list.
You can change the order of a feature
- by dragging it up and down the list with the
- mouse.
- The transparency slider setting (currently only available - in the application version) controls the visibility of features - rendered below other features. Reducing the transparency will mean - that features at the top of the list can obscure features lower - down, and increasing it allows the user to 'see through' the upper - layers of a set of features.
-You can save all features, with their current colours and visibility - in a Jalview format file. -

+Select View→Feature Settings... menu entry +in an alignment window to open the feature settings dialog box, which +allows you to precisely control the presence and appearance of sequence +features for the current alignment.

+The top section of the dialog box lists all the sequence feature +groups, along with a tickbox for each that controls whether its features +are displayed. The table in the middle lists all the features in the +currently selected groups, along with their display style and whether +they are currently being displayed (only the ticked features and groups +are displayed).

+ Selecting
+ alignment columns by feature
Double-clicking
+ a feature type in the Feature
+ Settings dialog allows you to select columns in the
+ alignment that contain (or do not contain) features of that type. If a
+ region of the alignment is currently selected, then only features in
+ the current selection will be searched. The following keys affect the
+ way in which selections are made:
Feature settings pop-up menu
+Right-click on a feature to open a pop-up menu that
+allows you to sort the alignment or current selection using that feature
+type (see below), or toggle the type of colouring used for the feature.
+Features may be highlighted with either a single colour or a feature colourscheme based on either the
+scores associated with that feature or from the feature's description
+(e.g. to distinguish different names associated with a DOMAIN feature).
Ordering alignment by features
+The 'Seq Sort by Score' and 'Seq Sort by Density' buttons will sort the
+alignment based on the average score or total number of currently active
+features and groups on each sequence. To order the alignment using a
+specific feature type, use the sort by .. entries in the pop-up
+menu for that type.
+Feature sorting and graduated feature colouring were introduced
+in Jalview 2.5

+The ordering of the sequence features in the dialog box list is

The Optimise order button (currently +only available in the application) will re-order the feature render +ordering based on the average length of each feature type.
