Manage the gate library

The gate library lists every named gate in the workspace, with its full version history. Use it to see which gate shape was live when, to give a gate a clearer name or description, and to archive gates nobody uses any more.

Where

Settings › Workspace Settings › Gates

Who

ManagerAdmin

Only Managers and Admins can edit or archive gates. Viewers and Operators have no Settings gear; the gates a series follows are visible to them on the samples themselves.

Gates are not created here. A gate is a shape drawn on a sample, so you create one — or a new version of one — in the gate editor: see Edit a gate.

The gate library. The expanded gate shows its shape, what changed against the previous version, and every version with the number of samples it counted.

What is on the page

Above the table:

• Search gates — filter by name.
• A type filter — All types, TCC-D or ICC-A.
• Show archived — include archived gates, marked Archived.

The table:

Column	Shows
	Opens the gate’s versions (see below).
Name	The gate’s name. Names are unique within the workspace.
Type	The sample type the gate is for: TCC-D (total cell count) or ICC-A (intact cell count).
Version	The live version, for example v2.
Updated	When the gate last changed.
Samples counted	How many samples have been counted with this gate, across all its versions.
Description	What the gate is for, or -.

Look through a gate’s versions

Select the arrow () at the start of a row. The row opens to show:

• The shape of the selected version, drawn as a polygon, with the HNA limit or ACC region where the sample type has one.
• What changed: the coordinates of each vertex (Now), with the previous version’s values (Was) beside anything that moved. A vertex that did not exist before is marked new.
• The versions: Version, Created, Samples counted and Note for each one. The version in use is marked Live. Select any version to see its shape.

The newest version is always the live one — creating a version is what makes it live. To go back to an earlier shape, draw that shape on a sample again. That adds a new version and keeps the history intact.

Edit a gate’s name or description

1. Open the Actions menu (⋮) at the end of the gate’s row and select Edit.

2. Change Name or Description.

3. Select Save.

Result: the message Gate updated appears. Only the name and description change; the shape and its versions do not.

Archive a gate

Archive a gate that no series follows any more, so it no longer clutters the library.

1. Open the Actions menu (⋮) on the gate’s row and select Archive.

2. Read the dialog. It says how many series follow the gate: Followed by 0 series means you can go ahead.

3. Select Archive.

Result: the message Gate archived appears and the gate disappears from the list. Turn on Show archived to see it again. Its versions stay, because the samples counted with them still refer to them. An archived gate cannot be edited or un-archived.

If it does not work

Message	What to do
Another gate already has this name	Choose another name.
Detach it from N series first - they would fall back to the device gating. (the Archive button is disabled)	Series still follow this gate. Point each of them at another gate first — see Edit a gate — then archive.
There is no Create button	Gates are created in the gate editor on a sample, not here.
