Hi again,
I see my problem. My matrix matp is NOT a t-stat, nor any other kind of statistic. It is just has one value per voxel. So I changed the type from FUNC to ANAT:
InfoDelOut.TYPESTRING = '3DIM_HEAD_ANAT';
InfoDelOut.SCENE_DATA(1) = 0; % orig view
InfoDelOut.SCENE_DATA(2) = 1 %1=some kind of anat, don't know difference btw them
InfoDelOut.SCENE_DATA(3) = 0; %for 3DIM_HEAD_ANAT types
The other thing I needed to do was change the scaling factor from 0 to 1:
InfoDelOut.BRICK_FLOAT_FACS=[1];
If I leave it at 0, it does not display the true value, but numbers from +/- 32700.
Thanks so much!
