Yes, brain is a 3d volume with beta weights from 3dDeconvolve for each subject.

So by voxel,

y = PTSD measure (continuous)
x = Exposure measure (continuous)

n=300

lm(formula = PTSD ~ Exposure*%signal change beta + age + sex + race_ethnicity + education + marriage status + income + device, data = dat)

Can 3dRegAna do interactions of this type? Or maybe 3dMEMA?
