Default structure viewer - choose JMOL or CHIMERA for viewing 3D structures.

Path to Chimera program - Optional, as Jalview will search standard installation paths for Windows, Linux or MacOS. If you have installed Chimera in a non-standard location, you can specify it here.

Viewing PDB Structures

- -

Jalview can view protein structures associated with a sequence -via the "Structure→" submenu from a -sequence's pop-up menu.

-A Jmol viewer has been included since Jalview 2.3. Jalview 2.8.2 added support for Chimera, -provided this has been separately installed. Choice of default viewer is configurable in the Preferences Structure tab. - -

+ Working with annotation from 3D structure data +
+
+ Jalview can process PDB data associated with sequences to display + values extracted from the Temperature Factor column for + corresponding sites, and secondary structure from DSSP or RNAView (as + appropriate). +
+
+ Extracting data from PDB files
Annotation is + created for structure files retrieved directly from the PDB loaded + from the file system (via the Structure→Associate + Structure...→From file option, or when displayed via the View + Structures Menu.
Structure annotation is not automatically + added to an alignment, but any available structure annotation rows for + the current selection or a particular sequence can be added via the Add + Reference Annotation in the Selection and Sequence + ID sub-menus of the Sequence ID Panel's popup menu.
Please + note:Protein structures are analysed + in situ, but Jalview employs a web service to process RNA + structures which can cause long delays if your internet connection is + slow. +
+
+ The Annotations + alignment menu provides settings useful for controlling the display + of secondary structure annotation. +
+
+ Shading sequences by associated structure annotation
The + annotation colouring dialog (opened by the Colour→By + Annotation option) allows sequences with associated secondary + structure data to be shaded according to secondary structure type. + Once the dialog is opened, select the Per Sequence option and + then choose Secondary structure from the dropdown menu.
When + colouring alignments by secondary structure, two modes can be + employed. The default is to shade sequences with the same colour as + the secondary structure glyph. If, however, original colours + is selected and another colourscheme has already been applied, then + only portions of the sequence with defined secondary structure will be + shaded with the previously applied scheme.
+
+
+ Configuration options for processing PDB files
+ Occasionally, you may wish to disable secondary structure processing. + Configuration options in the Structure tab in the Tools→Preferences + dialog allow the processing of structure data to be disabled, or + selectively enabled. For more information, take a look at the documentation for the structure panel. +
+
+ The display of secondary structure data was introduced in + Jalview 2.8.2, and is made possible by Jalview's use of Jmol's DSSP implementation, based on the + original Kabsch + and Sander algorithm ported by Robbie P. Joosten and + colleagues, and a client for Fabrice Jossinet's + pyRNA services that was developed by Anne Menard, Jim Procter and + Yann Ponty as part of the Jalview Summer of Code 2012. + +
