The full head dataset (colin_ICBMnorm.vmr) was selected in the main UI before invoking the rendering UI, and the background of the brain VMR was filled with a low value (30), and then selected as the secondary alpha channel, which makes all non-brain voxels appear with a very high transparency. | The full head dataset (colin_ICBMnorm.vmr) was selected in the main UI before invoking the rendering UI, and the background of the brain VMR was filled with a low value (30), and then selected as the secondary alpha channel, which makes all non-brain voxels appear with a very high transparency. | ||
