Foci
The Foci Tab in the Features Tool b ox contains options for display and selection of loaded and newly created foci on brain surfaces and in volumes.

- Display Foci toggles foci display on and off. When Foci Mode is turned on, Display Foci is NOT turned on by default.

- Group: identifies the Foci group for the Active Tab. Tabs assigned to the same Group will display the same foci with the same attributes.

- Foci Attributes contains options for viewing foci.

- Contralateral check box toggles on display of foci that are currently being displayed on one hemisphere to be displayed on the contralateral hemisphere (on top of that hemisphere's own displayed foci, if any).
- Paste Onto Surface moves the foci from their coordinate space to the nearest point directly on the surface displayed.
- Coloring sets the Class, Name or Standard Color as the foci color source.
- Standard Color selects the color when Coloring is set to Standard Color.
- Draw As sets the shape of the foci to Spheres or Squares.
- Symbol Diameter sets the size of the foci symbols.
