Figure 5From: Automatic analysis of 2D polyacrylamide gels in the diagnosis of DNA polymorphismsChanges in the brightness of a selected lane in the image L O . The difference between the brightness y P (m) calculated along the lane and its averaged result y G (m) is vital. Depending on the result of y P (m)-y G (m), the position of markers indicating subsequent bands is determined. The chart shows the range m k -m p which is the width of a sample band.Back to article page
