Fig. 5-10. Selecting a spot to landmark.
Select Landmark from the Match menu, Match toolbar, or right-click menu, and click
on the spot in the MatchSet Master.
The cursor will jump to the same area in the first member gel. If the landmarking
function can identify the same spot in that member, it will appear marked with a box.
Click it to place the landmark. Landmarked spots are marked with green triangles.
This appears as
one spot in some
gels, two in others.
This spot makes
a better landmark
because it is
well-resolved in
all gels.
