FCS Express supports seven types of gates.
•Elliptical gates: Gates that are oval, oblong, or circular.
•Rectangular gates: Gates that are square or rectangular.
•Polygonal gates: Gates that are drawn with three or more vertices connected by straight lines.
•Freeform gates: Gates that are drawn with various straight and/or curved sections in an irregular shape.
•1D gates: Gates that exist only in one dimension, i.e., a one parameter histogram gate or an x-axis plot gate.
•Well gates: Gates that are set on a heat map display showing the wells of a microtiter plate.
•Combination gates: Gates that are Boolean combinations of one or more of the other six types of gates.
•Quadrant Gates: Gates that are generally used to divide the plot content in 4 complimentary, and mutually exclusive, regions.
Examples of different gate types are shown in Figure 7.4.
