Although the seed voxel selection method based on the next local maximum approach yielded a relatively homogeneous distribution, a post-hoc analysis of the spatial distribution of the seed voxels in the three rs1006737 genotype groups showed a trend for differences in seed region localizations along the y-dimension at different rs1006737 genotype (ANOVA, F(2, 90) = 2.96, p = .057), which was significant if tested for a linear association with rs1006737 genotype (GG<GA<AA, r = .24, p = .023).
