8 <p><strong>DAS Sequence Feature Retrieval</strong></p>
9 <p>Jalview includes a client for retrieving sequences and their features via
10 the <a href="http://www.biodas.org">Distributed Annotation System</a>.</p>
12 <li>Open the Feature Settings panel by selecting "View ->
13 Feature Settings..."</li>
14 <li>Click on the "<a href="dassettings.html">DAS Settings</a>"
16 <li>Select the sources to use for DAS feature retrieval, then
17 click the "Fetch DAS Features" button.
19 <li>Cancelling Feature Retrieval<br>
20 Press the <strong>Cancel Fetch</strong> button to immediately stop
21 feature retrieval. This will not remove any features already added to
22 the alignment, but will halt any outstanding DAS requests.<em>The
23 cancel fetch button is of particular use when one or more DAS
24 annotation servers are not responding!</em>
28 <p>If your DAS source selection contains sources which use Uniprot
29 accession ids, you will be asked whether Jalview should find Uniprot
30 Accession ids for the given sequence names. It is important to realise
31 that many DAS sources only use Uniprot accession ids, rather than
32 Swissprot/Uniprot sequence names.<br>
33 The <a href="../webservices/dbreffetcher.html">database reference
34 fetcher</a> documentation describes how Jalview discovers what database
35 references are appropriate for the sequences in the alignment.
38 Please remember to save your alignment if either the start/end
39 numbering, or the sequence IDs were updated during the ID
40 retrieval process.</li>
43 <p><em>DAS support was introduced in Jalview Version 2.1.</em></p>
