Table 1.

Feature Groups.

	F1	F2	F3	F4		Fd1	Fd2	Fd3	Fd4
FG1	+	+	+	–	FG4	+	+	+	–
FG2	+	+	+	+	FG5	+	+	+	+
FG3	+	–	+	+	FG6	+	–	+	+

“+” means that the feature is present in the feature group, “−” indicates absence of feature. F₁, F₂, F₃, and F₄ are the maps of gray matter (GM) thickness, gradient, relative intensity, and gray/white matter boundary width map. F_d1, F_d2, F_d3, and F_d4 are the corresponding feature differences of F₁, F₂, F₃ and F₄.
