+PDB Viewer
+
+
+The Jalview internal PDB Viewer
+Since Jalview 2.3, the Jmol PDB Viewer is
+the main method for viewing PDB
+structures. The documentation below concerns the original Jalview
+PDB viewer, which is only used in situations where Jmol is unavailable
+or cannot operate.
+The PDB Viewer Window
+
This interactive structure viewing window is opened by selecting
+the "Sequence→View PDB entry:" entry in
+the sequence id pop-up menu. This
+can only be done for sequences which have an associated
+PDB structure, and the PDB Viewer will only be associated with the
+particular alignment view from which it was opened.
+Controls
+The structure is rendered as an alpha-carbon trace. Moving the
+mouse over the structure brings up tooltips with a residue name and PDB
+sequence position. If a mapping exists to a residue in the associated
+sequence, then this will be highlighted in the associated view in its
+alignment window, and vice versa for viewing the coordinates associated
+with a particular residue in the sequence in a particular view on the
+alignment.
+Selecting a residue highlights its associated sequence residue
+and alpha carbon location.

+There are three menus:
+
+ - File
+
+
+ - Save As
+ Saves the current view as an EPS or PNG file.
+ - View Mapping
+ Opens a text window showing the alignment between the
+ residues corresponding to alpha-carbon atoms in the PDB structure and
+ the residues in the associated sequence.
+
+
+ - Colours
+
+
+ - By Sequence
+ Colours each residue in the structure with the colour of its
+ corresponding residue in the associated sequence as rendered in the
+ associated alignment view, including any Uniprot sequence features or
+ region colourings.
+ Residues which only exist in the PDB structure are coloured white if
+ they are insertions (relative to the associated sequence in the
+ alignment) and grey if they are N or C terminal flanks outside the
+ region mapped to the alignment window's sequence.
+ - By Chain
+ Assigns a random colour to each PDB chain.
+ - Charge & Cysteine
+ Highlights cysteines in yellow, anionic (Aspartic Acid or
+ Glutamic Acid) residues in red, and cationic (Lysine or Arginine)
+ residues in blue.
+ - Standard and User Defined Jalview
+ colourschemes.
+ The remaining entries apply the colourschemes available from the
+ standard and user defined amino
+ acid colours.
+
+
+ - View
+ These options can be turned off to improve performance when
+ viewing large structures, some at the expense of visual clarity.
+
+ - Wireframe
+ Draws thin lines rather than thick lines for the
+ alpha-carbon trace.
+ - Depthcue
+ Shades the structure so parts of the structure near the front
+ of the view are brighter than those further away.
+ - Z Buffering
+ Applies depth sorting to correctly render occluded regions
+ of the backbone trace.
+ - Show All Chains
+ When turned on, shows all chains in the PDB file, not just
+ the one associated with a sequence in the alignment window.
+

+
+Notes for PDB Viewing in the Jalview Applet
+
The applet can only load PDB files by copying and pasting the
+text into the popup window which appears when "Show PDB
+Structure" is selected after right clicking on a sequence name.
