Nonparametric tests comparing lowest total entropy with default parameter for the standard method in SPM5

	SPM5 Standard Method Default Parameter versus Parameter with Smallest Total Entropy
	Nonlinear Frequency Cutoff	Nonlinear Regularization	Nonlinear Iterations
	25mm* versus 70mm	medium* versus heavy	16* versus 3
Control
p-value	p = 0.001	p = 0.001	p = 0.002
Diabetes
p-value	p = 0.001	p < 0.001	p = 0.013
Depressed Diabetes
p-value	p = 0.012	p = 0.012	p = 0.012
