2 <title>The BioJS MSA Templating System</title>
4 <h2>BioJS MSA Templates</h2>
5 <p>The Jalview Desktop uses a template file to embed data when
6 exporting an alignment as a BioJS MSA HTML page. This means it is
7 possible to update Jalview's template with different versions of the
8 BioJS MSA viewer, or even customise the page for your own needs.</p>
9 <p>NOTE: This is an experimental feature new in jalview 2.9 -
10 please get in contact with the developers if you're interested in
11 creating your own templates so we can improve this documentation !</p>
12 <h3>The components of a BioJS template file</h3>
14 <li>All JavaScripts necessary to render and visualise BioJS
16 <li>JavaScripts to transform BioJSON data to BioJS MSA data</li>
17 <li>Place holder for BioJSON data (this can be a div or input
18 element as show below): <pre>
19 <code><div name="seqData" id="seqData" style="display: none;">#valid BioJSON data#</div> OR
20 <input type="hidden" id="seqData" name="seqData" value='#valid BioJSON data#'/>
26 The externalised BioJS MSA templates are available in the Github
29 href="https://github.com/jalview/exporter-templates/tree/master/biojs">https://github.com/jalview/exporter-templates/tree/master/biojs</a>.
30 <br />Jalview processes the
31 <b>package.json</b> file at
33 href="https://github.com/jalview/exporter-templates/blob/master/biojs/package.json">https://github.com/jalview/exporter-templates/blob/master/biojs/package.json</a>
34 to work out the available versions of BioJS MSA Viewer templates and
35 the latest release version to use for its exports.
38 <h2>Creating/Updating a new BioJS MSA Template</h2>
39 The following steps can be taken to create or update a BioJS MSA
42 <li>Add/update all BioJS MSA scripts to the template file</li>
43 <li>Add/update codes for transforming BioJSON data to BioJS MSA
44 data (this requires knowledge of both data models)</li>
45 <li>Ensure that the new template created can be employed by
46 Jalview to generate valid BioJS MSA files. This can be achieved by
47 following the steps below to deploy the new export template to a
48 test repository and subsequently configure Jalview to use the test
49 repository for testing the template:
51 <li>Publish the template along with a valid package.json
52 file to an online repository</li>
53 <li>Configure Jalview preferences to point to the raw URL
54 of package.json in your test repository. This is done by
55 creating/changing the property <b>'biojs_template_git_repo'</b>
56 in the <b>jalview_properties</b> file <br />e.g. <b>biojs_template_git_repo=https://raw.githubusercontent.com/gituser/biojs-templates/package.json</b>
58 <li>Restart Jalview and ensure that the new templates are
60 <li>Export an alignment to BioJS MSA</li>
61 <li>Check that the exported file is valid and reflects all
62 the incorporated changes</li>
65 <li>Commit the new template to the official Jalview-BioJS
66 Github template repository <a
67 href="https://github.com/jalview/exporter-templates/tree/master/biojs">https://github.com/jalview/exporter-templates/tree/master/biojs</a>
69 <li>Update the package.json of the official template repository
71 href="https://github.com/jalview/exporter-templates/blob/master/biojs/package.json">https://github.com/jalview/exporter-templates/blob/master/biojs/package.json</a>
74 <li>Restore value for <b>'biojs_template_git_repo'</b> in
75 jalview_properties to point to the official template repository
77 <li>Repeat steps 3iii to 3v above</li>
