Difference Curve Chart

For easy visual identification of clusters, Precision Melt Analysis software generates a
difference curve for each well (Figure 26). The Difference Curve chart shows the difference in
fluorescence between a well and the fluorescence of a reference curve. The reference curve is
derived from the average fluorescence of all the curves within a selected reference cluster.
Select the reference cluster from the Reference cluster menu under the Difference Curve
chart.
