Hi Chris,
I had a problem of the overlapping color when I overlay two images.
When I run in one circumstance, the overlay color is yellow. The code I used is below:
BEGIN
RESETDEFAULTS;
MESHLOAD('BrainMesh_ICBM152_smoothed.mz3');
OVERLAYLOAD('.\Figure 3\rightPSTG_ALE_pN001.nii');
OVERLAYCOLORNAME(1, 'Winter');
OVERLAYMINMAX(1, 0.04, 0.08);
OVERLAYLOAD('.\Figure 3\meta_map_rightPSTGfinal.nii');
OVERLAYCOLORNAME(2, 'Red');
OVERLAYADDITIVE(true);
SHADERNAME('Minimal');
OVERLAYTRANSPARENCYONBACKGROUND(50);
SHADERXRAY(1, 0.3);
END.

However, when I tried to overlay another two images, the overlapping region color changed to purple.
The code I used is exactly the same as above but different files.
BEGIN
RESETDEFAULTS;
MESHLOAD('BrainMesh_ICBM152_smoothed.mz3');
OVERLAYLOAD('.\3_figure\Figure 3\leftASTG_ALE_pN001.nii');
OVERLAYCOLORNAME(1, 'Winter');
OVERLAYMINMAX(1, 0.06, 0.12);
OVERLAYLOAD('.\Figure 3\meta_map_leftASTGfinal.nii');
OVERLAYCOLORNAME(2, 'Red');
OVERLAYADDITIVE(true);
SHADERNAME('Minimal');
OVERLAYTRANSPARENCYONBACKGROUND(50);
SHADERXRAY(1, 0.3);
END.

I'm wondering if there are some way to control the color of overlapping?
Thanks,
