<strong>Sequence Fetcher</strong>
</p>
- <p>
- Jalview can retrieve sequences from certain databases using either
- the DBFetch service provided by the EMBL European Bioinformatics
- Institute, or, since Jalview 2.4, DAS servers capable of the <em>sequence</em>
- command (configured in <a href="dassettings.html">DAS settings</a>).
- </p>
- <p>The Sequence Fetcher can be opened via the "File"
+ <p>Jalview can retrieve sequences from a range of sequence, 3D
+ structure, genomic and domain family databases provided by EMBL-EBI.</p>
+ <p>The Sequence Fetcher 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. There may be a short delay
- when the sequence fetcher is first opened, whilst Jalview compiles
- the list of available sequence datasources from the currently
- defined DAS server registry.</p>
+ when the sequence fetcher is first opened, whilst Jalview contacts each database's web API.</p>
<p>
Every time a new fetcher is opened, you will need to <strong>select
the database you want to retrieve sequences</strong> from the database
tooltips are shown if you mouse over some sources, explaining what
the database will retrieve. You can select one by using the up/down
arrow keys and hitting return, or by double clicking with the mouse.
- <br />
- <em>If you have DAS sources enabled, then you may have several
- sources for the same type of sequence identifier, and these will
- be grouped together in a sub-branch branch labeled with the
- identifier.</em>
</p>
<p>Once you have selected a sequence database, its fetcher dialog
will open. Jalview provides two types of dialog:</p>
currently selected database into the retrieval box. Finally, press
"OK" to initiate the retrieval.</li>

- <strong>Only retrieving part of a sequence</strong>
- </p>
- <p>
- When using DAS sources (indicated by a "<em>(DAS)</em>"),
- you can append a range in addition to a sequence ID. For example, to
- retrieve 50 residues starting at position 35 in UNIPROT sequence
- P73137 using the UNIPROT DAS server, you would enter
- "'P73137:35,84'.<br /> <em>Full support for DAS range
- queries was introduced in Jalview 2.8</em>
