Sometimes, statistics are not enough. You want your report to display a result as text, not as a number. For instance, you would want your sample marked as positive or negative, depending on certain criteria.
FCS Express allows you to base your classification on any statistic, and create as many classification criteria as you like.
In the movie below, a Statistic Classifier will classify a sample based on the % viable cells. Watch as the layout dynamically updates as you change your gates.
