The two sequence views in &prog; show the forward and reverse strands of the
sequence and a representation of the three translation frames in each
direction.  The top view shows the subject sequence of the comparison (see
<XREF LINKEND="MAINWINDOW-BREAKDOWN-SUBJECT">), the bottom view shows the query
sequence (see <XREF LINKEND="MAINWINDOW-BREAKDOWN-QUERY">).  The horizontal
scrollbar controls which part of the sequence is currently visible.  The
scroll bar at the left controls the zoom level.  By default the view shows
only the stop codons in each translation frame, but if the view is zoomed in
it will show the complete six frame translation.

    <TITLE>Comparison View</TITLE>
    <PARA>
This part of the window shows the comparison between two sequences.  Each
red/pink box corresponds to single match, with red representing a good match
and white/pale pink a lower scoring match.  This view cannot be scrolled
directly, instead it tracks the movement of the subject and query sequence
views (see <XREF LINKEND="VIEWS">).

The vertical scrollbar at the right of the view sets the minimum size (in
bases on the subject sequence) of the matches that are displayed.  The default
is 1, so when started &prog; will show all matches.

      <PARA>
Clicking the left button on a match will highlight the match.  Double clicking
the mouse on one of the matches will cause the sequence views to align around
that match.

Clicking the middle mouse button toggles the locking of the two sequences that
are being compared by this comparison view.  When locked the sequences will
scroll in parallel.  When unlocked the sequences can be scrolled
independently.  (See <XREF LINKEND="MOUSEBUTTONS"> if you do not have a middle
mouse button)

The DNA plots are accessed from the Graphs(top) and Graphs(bottom) menus (see
<XREF LINKEND="DISPLAYMENU">).  When a graph is turned on it is locked to the
overview window, so it will follow the overview window when the overview is
scrolled.  It will also automatically change the viewing scale to match the
scale of the overview window.  The vertical scrollbar to the right of the
graph controls the window size of algorithm.
    </PARA>

    <PARA>
The feature plots window (see <XREF LINKEND="VIEWMENU-SHOW-FEATURE-PLOTS">)
has a horizontal scroll bar that sets the position of the plot in the feature.
As with the DNA plots, the vertical scrollbar to the right of the graph
controls the window size of algorithm.
    </PARA>

    <PARA>
Note that clicking the left mouse button on the plot will show the base or
residue at that position.  Clicking the right mouse button will pop-up a menu.
The menu contains a toggle which controls whether the graph is scaled and some
menu items which allow the maximum window size to be set.
