+<p><strong>Viewing PDB Structures</strong></p>\r
+<p>Jalview has a simple 3D structure viewer which can load PDB files and associate \r
+ the structure with a sequence in an alignment. </p>\r
+<p>There are 2 ways to load and associate a PDB file into Jalview application.</p>\r
+<ul>\r
+ <li>Select "<a href="seqfeatures.html">Sequence Features</a>" from \r
+ the "View" menu. This will attempt to match your sequences with \r
+ the Uniprot database first by name, then by sequence. The same process will \r
+ make note of any PDB files associated with each sequence. </li>\r
+ <li>Select "<a href="seqfetch.html">Fetch Sequence</a>" from an alignment \r
+ window or from the main desktop "File" menu. In the popup window \r
+ which appears, select PDB as the database and enter your known PDB id. If \r
+ you know which chain you wish to retrieve, append the chain id after a colon \r
+ eg 1GAQ:B</li>\r
+</ul>\r
+<p>Note the applet can only load PDB files by copying and pasting the text into \r
+ the popup window which appears when "Show PDB Structure" is selected \r
+ after right clicking on a sequence name.</p>\r
+<p>To see a particular structure, right click on a sequence name and from the \r
+ popup menu select "Sequence -> View PDB Entry". </p>\r
+<p>The PDB Structure viewer will perform a pairwise alignment of your sequence \r
+ and each PDB chain sequence. To view the results of the mapping, select "File \r
+ -> View Mapping" from the structure viewer window. </p>\r
+<p>Moving the mouse over the structure will highlight the residue in the alignment \r
+ window, and vice versa.</p>\r
+<p><em>Tips for Viewing Structures</em></p>\r
+<ul>\r
+ <li>Colour By Sequence follows the exact colours of the alignment window, including \r
+ sequence features. Thus you can easily view Uniprot sequence features, eg \r
+ helix or metal binding sites on both the alignment and structure viewer.</li>\r
+ <li>Deselect Colours->Show All Chains in order to view only the mapped chain. \r
+ </li>\r
+ <li>Use Wireframe, without depthcue, and without Z Buffering in order to accelerate \r
+ the rendering of the structure. </li>\r
+ <li>You can save an image of your structure as a PNG or EPS file.</li>\r
+</ul>\r
