+The application provides three ways to access the retrieval function. Either:\r
+<ul><li>select the <strong>Discover PDB IDs</strong> option from the structure submenu of the sequence's popup menu</li>\r
+<li>Select one of the options from the alignment window's <strong>Web Services</strong> menu to fetch references from either the EBI databases plus currently selected DAS sources, or an individual database source</li>\r
+<li>Answer 'Yes' when asked if you wish to retrieve database references for your sequences after initiating a DAS Sequence Feature fetch.</li>\r
