Annotate with secondary structure from PDB

I have a sequence in an alignment of which I have associated with a PDB structure ID. Is there a way to extract the secondary structure information from the structure and display it as an annotation in the alignment (like the Jnet prediction output).

Thanks,
-Mark

Hi Mark.

If you are using Jalview 2.8.2 (or later), then there is a way. First, open your Preferences and navigate to the 'Structures' tab, and make sure you have ticked the 'Process secondary structure from PDB' option.

nb. A number of other options will also become available - these control whether you want to get RNA secondary structure (which can take some time since) and whether you want to always add secondary structure and temperature factor annotations to the alignment. For proteins, the important thing is checking 'process secondary structure'.

Now, open the alignment and make the PDB association (or, if you've already got an association in a jalview project, simply open that). Then, open a Jmol view of the structure via the Structures submenu of the popup menu. Once the structure has been loaded and displayed, you can show the secondary structure for a particular sequence or a selected set on the alignment by selecting the 'Add reference annotation' option from the Sequence ID or the Selection submenus in the popup menu.

Here's the online version of the built in help for this: http://www.jalview.org/help/help.html

Let us know how you get on !

Oops - gave you the wrong link. Here's the structure annotation page:

Hi Mark,

You may find that this procedure fails if you use option "Associate Structure with Sequence | Discover PDB ids".

It should work correctly after "Associate Structure with Sequence | Enter PDB Id".

Let us know if you are still having trouble!
