Why don the numbers from the model and gates match?
The proliferation modeler constructs a series of Gaussian curves, the sum of which equals the distribution found in the data file. In the model, the tails of the curves will overlap, and those are added with the other curves. When gates are produced, hard boundaries are imposed at the points where the tails intersect, and the events are distributed into the population whose peak is closest to their position. This is not the same as the way the theoretical model is overlapping, and hence the totals will be different.
