Data analysis tools

[Gate] group

The [Gate] group contains controls for creating and editing gates.
Gates allow you to identify and analyze populations of interest by isolating a region in a selected plot. They can
also be used to limit the number of events collected.
The types of gates available are [Rectangular], [Polygon], [Ellipsoid], [Marker], [Quadrant], [S-Quadrant], and
[Boolean].
With gating tools, you can also change the color of a population, set the gate hierarchy, or create gates based
on Boolean operators (i.e. derived gates) by combining already defined gates.
You can create a maximum of 50 gates per workarea. Once this number is reached, a new gate cannot be
created.

Note:
• You can also right-click on a plot and click
(Gate) to quickly access the tool for making changes on
the plot.
• You cannot add a new Quadrant or S-Quadrant gate if the number of gates is already 47 or more.

[Gate] group

The [Gate] group contains the options below.
[Rectangular]

You can insert a [Rectangular] gate into a selected dual-parameter plot. To
insert the gate, select the desired plot, and click the [Rectangular] button
and the position in the plot where you want the top-left corner of the gate to
be. To resize, press and hold the mouse button while dragging the points
until the gate is the size you want. Release the mouse button to complete
the gate.
You can also drag the rectangle to change the position while maintaining
its shape.

[Polygon]

You can insert a [Polygon] gate into a selected dual-parameter plot. To
insert the gate, select the desired plot, click the [Polygon] button and the
position on the plot where you want the first vertex to be, then click and
release the mouse button. Continue to click on the plot to add additional
points to the polygon to draw the gate around the population of interest. To
complete the process, click the square of the first polygon vertex.
When completed, and you click on the gate, in addition to the vertices
being marked, the polygon will show four outer squares which can be used
for proportional resizing. You can also drag on the polygon to change the
position while maintaining its shape.
