-<p><strong>Sequence Fetcher</strong></p>
-<p>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 <em>sequence</em>
-command (configured in <a href="dassettings.html">DAS settings</a>).</p>
-<img src="seqfetcher.gif" align="center"
- alt="The Jalview Sequence Fetcher Dialog Box">
-<p>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. Please note, there
-will 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.</strong></p>
-<p>First, select the database you want to retrieve sequences from.
-Then, 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.</p>
-<p><em>Fetching Individual PDB Chains</em><br>
-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
-:<br>
-<pre> 1GAQ:A</pre>
-</p>
-<p><em>Retrieving parts of large sequence records</em><br>
-When retrieving from DAS sequence sources, coordinate range arguments
-can be passed to the server using the standard DAS sequence command
-format:<pre>
- <AccessionId>:<start>,<end></pre> If you know a source
-understands this type of query format, then you should untick the
-checkbox for 'replace commas with semi-colons' so the range query can be
-passed to the server; otherwise, the query will be split into two (e.g
-'Mito:1' and '85779' rather than 'Mito:1,85779'). In most cases,
-however, a source that supports range queries will include a range
-qualification in its example query, and Jalview will then automatically
-disable the 'replace commas with semi-colons' option.<br>
-<em>The option to disable the comma to semi-colon translation was
-added in Jalview 2.6</em></p>

-Uniprot, PDB and PFAM) in work for publication, please cite:</p>

+ <strong>Sequence Fetcher</strong>
+ </p>
+ <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 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
+ chooser.
+ </p>
+ <img src="selectfetchdb.gif" align="left" width="480" height="204"
+ alt="Database selection dialog for fetching sequences (introduced in Jalview 2.8)">
+ <p>
+ The databases are shown as a tree, and ordered alphabetically;
+ 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.
+ </p>
+ <p>Once you have selected a sequence database, its fetcher dialog
+ will open. Jalview provides two types of dialog:</p>
+ <ol>
+ <li><strong>The Free-text Search Interface</strong> <br />Free-text
+ search clients are provided for PDB (Since 2.9), and UniProt
+ (Since 2.10). They provide access to each database's own query
+ system, enabling you to retrieve data by accession, free text
+ description, or any other type of supported field. For full
+ details, see each client's help page:
+ <ul>
+ <li><a href="pdbsequencefetcher.html">PDB Sequence
+ Fetcher</a></li>
+ <li><a href="uniprotsequencefetcher.html">UniProt
+ Sequence Fetcher</a></li>
+ </ul></li>
+ <li><strong>Accession based sequence retrieval</strong> <br />
+
+ <img src="seqfetcher.gif" align="center"
+ alt="The Jalview Sequence Fetcher Dialog Box"><br /> To
+ retrieve sequences, simply <strong>enter one or more
+ accession ids</strong> (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.</li>
