Parameters used for the ANIMAL algorithm for human subcortical group-wise nonlinear transformation estimation

Generation	Step size (mm)	Iterations	Gaussian blur (mm)
1	8	50	16
2	8	20	8
3	4	20	8
4	4	20	4
5	2	20	4
6	2	20	2

All values for lattice diameter were set to 1.5 × Step_size. Regularization parameters of stiffness, weight, and similarity were set to 1, 1, and 0.3, respectively (as per {Robbins et al., 2004, Med Image Anal, 8, 311-23}). In all cases intensity features extracted from the blur were used.
