Shows the basic AHEAD processing pipeline. For the first step of the pipeline shown on the left side of this image, subjects were aligned to our template via a rigid body transform. Next, shown in the middle of the figure test subjects were aligned to our training brains. This yielded 60 warps for both the left and right amygdala (20 training brains × three levels of detail). As shown on the right side of the figure, amygdala masks were projected from the training brains and combined in a weighted average. The match between training and test determined the weighting for each amygdala mask.
