Sequence Fetcher
Jalview can retrieve sequences from certain databases using either the -WSDBFetch service provided by the European Bioinformatics Institute, and, since Jalview 2.4, DAS servers capable of the sequence command (configured in DAS settings).
-The Sequence Fetcher dialog box can be opened via the "File" +WSDBFetch service provided by the European Bioinformatics Institute, or, since Jalview 2.4, DAS servers capable of the sequence command (configured in DAS settings).
+The Sequence Fetcher dialog box can be opened via the "File" menu on the main desktop in order to retrieve sequences as a new alignment, or opened via the "File" menu of an existing alignment - to import additional sequences.

+Once you have selected the sequence database using the popup dialog box, enter one or more accession ids (as a semi-colon separated list), or press the "Example" button to paste the example accession for the currently selected database into the retrieval box. Finally, press "OK" to initiate the retrieval.

Since Jalview 2.x.x if PDB is selected as the sequence database, a specialised interface - PDB Sequence Fetcher is used for discovering and retrieving the sequenec data.
+Specifying chains for PDB IDs
If you are retrieving sequences from the PDB, you can retrieve
specific chains by appending a colon and the chain id to the PDB
- id. For example :
1GAQ:A

+ specified in addition to a sequence ID. To retrieve 50 residues
+ starting at position 35 in UNIPROT sequence P73137 using the UNIPROT
+ DAS server, you would enter "'P73137:35,84'.
Full support for DAS range queries was introduced in Jalview 2.8
