<p><strong>DAS Settings</strong></p>\r
-<p>Jalview can retrieve features from multiple <a href="http://biodas.org/">DAS</a> \r
- sources. The DAS sources are selected in the DAS settings panel.</p>\r
+<p>Jalview can retrieve and visualize features from many <a href="http://biodas.org/">DAS</a> \r
+ sources at once. The DAS sources are discovered and selected <em>via</em> the DAS settings panel.</p>\r
<p><img src="das.jpg" width="497" height="365">\r
-<p>On start up of the DAS Settings panel, Jalview will use the registry URL (default \r
- is http://das.sanger.ac.uk/registry/das1/sources/) to retrieve a list of currently \r
- available DAS sources. These are all listed in the table using the sources' \r
- Nickname as an identifier. <br>\r
- Click on a Nickname in the table to reveal more information about that service \r
- in the panel to the right of the table. \r
+<p>The available sources are listed in the table using each source's\r
+Nickname as its identifier. Clicking on a source's entry in the table\r
+reveals more information about that service in the panel to the\r
+right. Select the tickbox in the "Use Source" column for a\r
+source to add it to the set Jalview queries for alignment and sequence\r
+features.\r
+</p>\r
<p>You can filter the visible DAS sources by authority, type and "label". \r
You should read the DAS documentation to understand more about these values.\r
-<p>Tick the box "Use Source" so that Jalview will use a particular source \r
- when fetching features. \r
+<p><strong>Updating the list of sources</strong></p>\r
+<p>When the DAS Settings panel is first opened, and when the <strong>'Refresh\r
+ source'</strong> buton is pressed, a list of DAS sources\r
+ is retrieved from the DAS registry URL (set by default to the DAS\r
+ registration server at\r
+ http://das.sanger.ac.uk/registry/das1/sources/).</p>\r
+<p><strong>Adding your own DAS Sources</strong></p>\r
<p>You can add your own DAS source to the list by clicking the "Add Local \r
Source" button. Enter the URL and nickname of your additional service. \r
It should be noted that Jalview 2.1 will not query additional sources for more \r
