Alexander, When creating an ellipsoid from a fiducial surface, there is no way to control the dimensions of the resulting ellipsoid. The operation tries to scale the surfaces created so that they have a surface area close to that of fiducial surface.
You could do the following: * Place the ellipsoid surface in the main window. * Select Surface Menu->Information to the get the XYZ extents of the surface. * Determine the X, Y, and Z scaling needed to make the ellipsoid the size that you desire. * Select Window Menu->Transformation Matrix Editor. * Enter the X, Y, and Z scaling values that you calculated. * Press the Apply Matrix to Main Window Menu. Check the box next to Main Window Surface in the pop-up dialog, and press the OK button. Good luck. ----------------------------------- John Harwell [email protected] Department of Anatomy and Neurobiology Washington University School of Medicine 660 S.
