The original trace data from which the readings where derived can be seen by double clicking (two quick clicks) with the middle mouse button on the area of interest. The trace will be displayed centred around the base clicked upon and the name of the reading in the contig editor will be highlighted. Double clicking on the consensus instead of a reading displays up to four readings overlapping that point.
The picture shows an example of two displayed traces. On the left is
the name of the reading and two buttons to display information and
quit. Pressing the info button will bring up the window displayed in
the bottom right of the picture. It will contain the comments from the
readings' SCF file. Between these buttons and the trace
display itself are two vertical scale bars. Moving these will zoom the
traces in the X or Y direction. The default Y scale is to fit the highest
peak on the screen without clipping.
The trace is displayed on the right with a scrollbar
directly above it. The vertical line seen in these two traces shows
the location of the editing cursor in the contig editor window. The
lock button on the trace displays ties the editing cursor movement to
scrolling of the trace windows. However the converse is not true;
scrolling the traces with lock set does not move the editing cursor.
The trace display can only display four traces at once. When
new traces are requested the oldest displayed trace (at the top of
the trace window) is removed and the new trace added to the bottom.
Traces can be removed individually by using the "quit" button in the
panel to the left of the trace.
Resizing the width of the trace window, moving the trace window and
adjusting the X magnification are all remembered and used when bringing
up new trace displays.
