-<p><strong>Viewing PDB Structures</strong></p>\r
-<p>Jalview has a simple <a href="pdbviewer.html">3D structure viewer</a> which can visualize polypeptide backbone\r
- structures associated with a sequence in an alignment. It is\r
- accessed via the <strong>"Sequence→View PDB\r
- entry:"</strong> entry from the sequence's <a\r
- href="../menus/popUp.html">pop-up menu</a>.</p>\r
-<p>There are two ways to associate PDB files with sequences:</p>\r
-<ul>\r
- <li>Select "<a href="seqfeatures.html">Sequence Features</a>" from \r
- the "View" menu, which retrieves any uniprot sequence\r
- records associated with the sequences in the alignment. If, for a\r
- particular sequence's uniprot record there\r
- are any cross-references to PDB structures, then these will be\r
- added to its list of associated database ids.</li>\r
- <li>Retrieve sequences from the PDB using the <a\r
- href="seqfetch.html">Sequence Fetcher</a>. Any sequences retrieved\r
- with this service are automatically associated with their source\r
- database entry. For PDB sequences, simply select PDB as the database\r
- and enter your known PDB id (appended with ':' and a chain code, if\r
- desired).</li>\r
-</ul>\r
-For help on viewing and colouring structures see the <a\r
-href="pdbviewer.html">PDB Viewer</a> help page. \r

+<p><strong>Viewing PDB Structures</strong></p>
+<p>Jalview can view protein structures associated with a sequence via the <strong>"Structure→View
+ PDB entry:"</strong> entries from a sequence's <a
+ href="../menus/popupMenu.html">pop-up menu</a>. This will open an
+ interactive display of the structure in a new window, or prompt you
+ to associate the sequence with an existing view of the selected
+ structure. See the <a href="jmol.html">Jmol PDB viewer</a> help page
+ for more information about the display.
+</p>
+<p>To associate PDB files with a sequence, right click on a sequence ID and select
+ "Structure<strong>→</strong> Associate Structure with Sequence",
+ and one of the submenus:</p>
+<ul>
+ <li>From File - You can load a PDB file from the local machine or network and
+ associate it with the selected sequence. PDB files associated in this way
+ will also be saved in the <a href="jalarchive.html">Jalview Archive file</a>. <br>
+ </li>
+ <li>Enter PDB Id - Jalview will use WSDBFetch, provided by the EBI, to fetch
+ the PDB file with the entered Id.<br>
+ </li>
+ <li>Discover PDB Ids - Jalview uses WSDBFetch, provided by the EBI, to discover
+ PDB ids for all the sequences in the alignment which have valid Uniprot names
+ / accession ids. </li>
+</ul>
+<p><strong>Importing PDB Entries or files in PDB format</strong><br>
+You can retrieve sequences from the PDB using the <a
+ href="seqfetch.html">Sequence Fetcher</a>. Any sequences retrieved with this
+ service are automatically associated with their source database entry. For PDB
+ sequences, simply select PDB as the database and enter your known PDB id (appended
+ with ':' and a chain code, if desired).
+<br>Jalview will also read PDB files directly. Simply load in the file
+as you would an alignment file. The sequences of any peptide chains
+will be extracted from the file and viewed in the alignment window.
+<br><em>Note for jalview applet users: due to the applet security
+constraints, PDB Files can currently only be imported by cut and paste
+of the PDB file text into the text box opened by the 'From File' entry
+of the structure menu.</p>
+<p><strong>Viewing the PDB Residue Numbering</strong><br>
+Sequences which have PDB entry or PDB file associations are annotated
+with sequence features from a group named with the associated PDB
+accession number or file name. Each feature gives the corresponding
+PDB Residue Number for each mapped residue in the seuqence. The
+display of these features is controlled through the
+<strong>"View→Sequence Features"</strong> menu item
+and the <a href="featuresettings.html">Feature Settings dialog
+box</a>.</p>
