Hi John, The "size" in spreadsheet gets placed in the focus' "extent" attribute which could be number of voxels or volume (millimeters cubed) of voxels in an activation.
On the Display Control's Foci Main Page is a "Foci Size" control. It affects the size of all foci. Each focus is mapped to a focus color and each focus color has a point size attribute. Select Layers Menu->Foci->Edit Foci Colors. Select the color used by a focus, adjust its Point Size, and then press the Color File Editor's Apply button. Be sure to save the foci color file.
