+ <strong>DAS Sequence Feature Retrieval</strong>
+ </p>
+ <p>Jalview includes a client for retrieving sequences and their
+ features via the Distributed Annotation System.</p>
+ <ol>
+ <li>Open the Feature Settings panel by selecting "View
+ -> Feature Settings..."</li>
+ <li>Click on the "<a href="dassettings.html">DAS
+ Settings</a>" tabbed pane.
+ </li>
+ <li>Select the sources to use for DAS feature retrieval, then
+ click the "Fetch DAS Features" button.
+ <ul>
+ <li>Cancelling Feature Retrieval<br> Press the <strong>Cancel
+ Fetch</strong> button to immediately stop feature retrieval. This
+ will not remove any features already added to the alignment,
+ but will halt any outstanding DAS requests.<em>The cancel
+ fetch button is of particular use when one or more DAS
+ annotation servers are not responding!</em>
+ </ul>
+ </li>
+ </ol>
+ <p>
+ If your DAS source selection contains sources which use UniProt
+ accession ids, you will be asked whether Jalview should find UniProt
+ Accession ids for the given sequence names. It is important to
+ realise that many DAS sources only use UniProt accession ids, rather
+ than Swissprot/UniProt sequence names.<br> The <a
+ href="../webServices/dbreffetcher.html">database
+ reference fetcher</a> documentation describes how Jalview discovers
+ what database references are appropriate for the sequences in the
+ alignment.
+ <ul>
+ <li><em>Note</em><br> Please remember to save your
+ alignment if either the start/end numbering, or the sequence IDs
+ were updated during the ID retrieval process.</li>
+ </ul>
+ <p>
+ <p>
+ <em>DAS support was introduced in Jalview Version 2.1.</em>
+ </p>
+ <br />
+ <p>
+ <em>The DAS registry at http://www.dasregistry.org was
+ decommissioned early in 2015. An unmaintained mirror is currently
+ hosted at http://www.ebi.ac.uk/das-srv/registry/.</em>
