Hence, using a biexponential transformation provides a more precise visualization tool when comparing populations with low . Since your xdata are mostly much greater than 10, for example, your true lambdas must be much less than 1/10 Otherwise, your fitted curve will be essentially zero almost everywhere. Jan 23,  · Graphically and mathematically it is easy to see they are inverses. One principle reason for using these equations to transform data is that flow cytometry data are traditionally displayed on a log scale. Other types of biexponential scaling exist, including Hyperlog.

If the FCS file doesn't have valid biexponential scales then the scales are calculated from the entire data. By applying a biexponential transform to the data, the scale is compressed in the lower range, typically from or , leading to a more accurate visual representation of fluorescence units in the low range of the scale as compared to the higher range of the scale. Biexponential / Logicle Display Biexponential display is an important feature when visualizing compensated data.D.
