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.

Because the fluorescence parameters are displayed on a log scale (on which it is not possible to display zero or negative values), the accumulation of cells on the axis makes it impossible to judge whether compensation is set correctly.

† Display a grid on the worksheet that is scalable. • Biexponential display is enabled by default, but can be disabled in user biexponential scale manual preferences, allowing more events to be recorded per experiment. These artifacts are largely avoided in the Biexponential and Hyperlog displays. Biexponential Model: The Sum of Two Exponentials. Once the two exponentials have been computed, the biexponential function value and the first two derivatives can be computed with only a few more multiplications and [HOST] by: Increase the scale on FSC-A until you see clear populations.
