22 <head>Opening URLs from Jalview
27 <strong>Opening URLs from Jalview</strong><br> Both the applet
28 and the desktop application are able to open URLs as 'popups' in
29 your web browser. <br> Double-clicking on the ID of a sequence
30 will open the URL designated for 'popups' in the "Connections" tab of the <a
31 href="../features/preferences.html">Jalview desktop
33 This is by default the EMBL-EBI site, but you can easily configure your own <a
34 href="#urllinks">sequence URL links</a>.
37 Other links for a sequence either derived from any other configured
38 URL links, or imported from the sequence's annotation, are accessed
39 by right clicking to open the sequence pop-up menu, and selecting
40 from the <em>Links</em> submenu.
43 <strong><a name="urllinks">Configuring URL Links</a></strong> <br>URL
44 links are defined in the "Connections" tab of the <a
45 href="../features/preferences.html">Jalview desktop
46 preferences</a>, or specified as <a
47 href="http://www.jalview.org/examples/appletParameters.html#parameters">applet
50 By default, the list of available links in the preferences dialog box
51 contains the item "EMBL-EBI Search",
52 which is set as the URL which opens on double-clicking on a sequence ID, and as a
53 menu item in the Links menu. This link will show a web page in your default
54 browser with the selected sequence id as part of the URL.
56 Also by default, the list of available links contains persistent URLs for many common
57 bioinformatics databases. These links are downloaded by Jalview from
58 the <em>identifiers.org</em> website, and the names and URLs are not user editable.
60 The list of links is sortable, by clicking on the headers of the table. The list
61 can be filtered using the free text search box below the table, or the
62 "Custom Only" button, which displays only user-defined links.
65 In the preferences dialog box, the links which appear in the Links menu
66 can be configured by selecting or deselecting links in the "In Menu"
67 column. The names of selected links will be displayed
68 on new menu items under the "Link" menu when you right
69 click on a sequence id.<br>
70 You can configure which link is used when double-clicking on a sequence
71 by selecting or deselecting links in the "On Click" column. Exactly one
72 link must be configured for double-clicking. Since the link uses the sequence id
73 to construct the URL to open, the selected link must contain the
74 "$SEQUENCE_ID$" token (see below for details of the "$SEQUENCE_ID$"
75 and other tokens).</p>
77 Additionally you can click <strong>new</strong> to add a
78 new link, and <strong>edit</strong> to modify an existing link, or <strong>delete</strong>
79 to remove it. Only URLs entered by the user (or the default EMBL-EBI link) may
80 be edited or deleted. When adding or editing a link, the URL string must contain a
81 token that can be replaced with a sequence ID or DB accession ID. The simplest token is
82 "$SEQUENCE_ID$", which will be replaced by the chosen
83 sequence id when you click on it.

88 Swissprot = http://www.expasy.org/uniprot/$SEQUENCE_ID$ <br> <br>
89 Links will also be made for any database cross references associated
90 with the sequence where the database name exactly matches a URL link
91 name. In this case, the $DB_ACCESSION$ string will be replaced with
92 the accession string for the database cross-reference, rather than
93 the sequence ID for the sequence (<em>since Jalview 2.10.1</em>).
96 <strong><a name="warning">Warning dialog about updating
97 your configured URL links</a></strong><br /> In the desktop
98 prior to Jalview 2.10.1, the only way to configure custom links for
99 a particular database cross-reference for a sequence was to give it
101 <em>exactly</em> matched the database source, and a regular
102 expression for filtering out any spurious matches generated when the
103 custom linked was tested against the Sequence's ID string. Since the
104 introduction of the $DB_ACCESSION$ token, however, $SEQUENCE_ID$
105 will not be used for database cross-reference accession strings, and
106 if you have custom links configured, Jalview will raise a warning
107 message so let you know that you may need to update your links to
111 <strong>Regular Expression Substitution</strong><br> A url may
112 contain a string of the form $SEQUENCE_ID=/<em>regular
113 expression</em>/=$ or $DB_ACCESSION=/<em>regular expression</em>/=$.
114 In this case, the regular expression will be
115 applied to the full sequence ID or DB accession ID string and the resulting match will
116 be inserted into the URL. Groups of parentheses can be used to
117 specify which regions of the regular expression will be used to
120 <li>Each top level parenthesis will yield a URL containing the
121 text matched within that parenthesis.</li>
122 <li>Regions matching sub-parentheses within a top-level
123 parenthesis will be concatenated to form the text inserted into
124 the URL for the top-level parenthesis.</li>
127 <li>The regular expressions supported by Jalview are those
128 provided by the <a href="http://www.javaregex.com">Stevesoft
129 javaregex package</a>.
131 <li>Some characters must be escaped when specifying them as
132 a match within a regular expression.</li>
133 </ul> <br> Many Thanks to Bernd Brandt of the Free University of
134 Amsterdam for testing this new regular-expression expansion
