One of the many timesaving features that FCS Express offers is the
ability for you to gate on a quadrant. This was a highly requested
feature and is useful if you want to use your quadrants to set a
negative (or positive) population and have your other plots only show
cells in that population.
You can easily convert a quadrant to a gate with a click of a button,
and then use the resulting gate in the same way as any other gate,
for example in a gate formula. While creating the gate, you can
choose whether or not to link it.
gate is like a regular gate, but its borders change whenever you
modify the quadrant that you originally created it from.
Histogram markers can also be converted to
gates and linked!
