Hi Fariba, you can scale the sphere to have the same surface area as the ?h.white, then use great circles on it. cheers Bruce On Mon, 11 Apr 2011, Fariba Sharifian wrote: > Hi, > How should I have the distance between two points in mm? > If I use the ?h.sphere, as all the spherical surfaces ar

Yes, it should be the same across all subjects. You only need to do it for designs that use an assumed shape (-gammafit). doug Katie Bettencourt wrote: > Ok, I ran that and a couple questions. I ran it on 2 different > subjects and got the exact same value, is that expected? Do I need to > ru
