Population Tree

The Gating Editor is where you create gates and populations. It has gating tools and plot in the middle. Gates are listed on the left side of the page. On the right side of the Gating Editor is our gating control panel with three tabs: Population tree, Boolean expressions and Sunburst view.

Description automatically generated

The Population tree displays the populations in hierarchical order, with each population nested under the proper parents. For each population at a given level, there is the gate name and the percentage of parent and the event number. If you hover over a particular level, you will get a set of icons to edit the name, copy, or delete the corresponding population. 

You can also click on a population or set of populations to select it/them. There will be a menu with options that appear to allow you to Unselect, add a Prefix, add a Suffix, Copy all the populations, or Delete them.

The populations created within the Boolean expressions tab will show up in the Population tree with the corresponding hierarchy (see article on Boolean Gating for more details). 

In some situations when copying a population, you may see the child populations from the original parent are now placed under the cloned population. This happens when the populations are created using only gates and has only AND logic. When it is cloned, it has identical gates and creates ambiguity. In the population tree, it would place such ambiguous children under the parent with the last name alphabetically.
