27 <strong>Sequence Fetcher</strong>
30 Jalview can retrieve sequences from certain databases using either
31 the DBFetch service provided by the EMBL European Bioinformatics
32 Institute, or, since Jalview 2.4, DAS servers capable of the <em>sequence</em>
33 command (configured in <a href="dassettings.html">DAS settings</a>).

36 alt="The Jalview Sequence Fetcher Dialog Box"
38 <p>The Sequence Fetcher dialog box can be opened via the
39 "File" menu on the main desktop in order to retrieve
40 sequences as a new alignment, or opened via the "File"
41 menu of an existing alignment to import additional sequences. There
42 may be a short delay when the sequence fetcher is first opened,
43 whilst Jalview compiles the list of available sequence datasources
44 from the currently defined DAS server registry.</p>
46 First, <strong>select the database you want to retrieve
47 sequences from</strong> by clicking the button labeled 'Select database
48 retrieval source'. If a database source is already selected, then
49 the button's label will change to show the currently selected

53 alt="Database selection dialog for fetching sequences (introduced in Jalview 2.8)"
55 <p>Since Jalview 2.8, the available databases are shown as a tree
56 in a popup dialog box. The databases are ordered alphabetically, and
57 if there are many sources for the same type of sequence identifier,
58 they will be grouped together in a sub-branch branch labeled with
61 Once you have selected the sequence database using the popup dialog
62 box, <strong>enter one or more accession ids</strong> (as a
63 semi-colon separated list), or press the "Example" button
64 to paste the example accession for the currently selected database
65 into the retrieval box. Finally, press "OK" to initiate
69 <strong>Fetching from The PDB with the EMBL-EBI PDBe Search
73 Since Jalview 2.9, selecting PDB as the sequence database will open
74 the <a href="pdbsequencefetcher.html">PDB Sequence Fetcher</a> for
75 discovering and retrieving structures.
78 <strong>Only retrieving part of a sequence</strong>
81 DAS sources (indicated by a "<em>(DAS)</em>") allow a
82 range to be specified in addition to a sequence ID. To retrieve 50
83 residues starting at position 35 in UNIPROT sequence P73137 using
84 the UNIPROT DAS server, you would enter "'P73137:35,84'.<br />
