There
are many times when it is useful to attach additional or external
information to a node in the workspace. This may be handled in FlowJo
through the workspace annotations.
To annotate one or more nodes, select them in the
workspace and invoke the Set Annotations... command from
the Workspace menu.
You will see a simple dialog with an editable field.
Type the annotation into this box, click OK and the annotation will
be attached to all of the selected nodes in the workspace.

There is a preference defined to import the information
from the FCS file header. The FCS specification
defines a $COM field for comments. If the (Preference
for Copy $COM to annotation is checked then the workspace annotation
field will be initialized with the keyword's value as samples
are included. Note that any node can have an annotation, but only
the top level sample nodes will ever receive information from
the FCS file.
In the layout editor,
graphs will show the node's annotation. To enable or disable this
functionality, double click on a graph in the layout, and click
on the Annotate pane. There is currently
no functionality to export annotation information via the table
editor. That will be implemented in a future release.
