Hello, I need some help about 3dRegAna. I am doing a two-way ANOVA with unbalanced data. Below is a sample of my model (columns are factor a, factor b, and axb respectively).
3dRegAna \
-rows 39 \
-cols 3 \
-xydata 0 0 0 subj1.nii \
-xydata 0 1 0 subj2.nii \
-xydata 1 0 0 subj3.nii \
-xydata 1 1 1 subj4.nii \
...
-model 1 2 3 : 0 \
I observed significant axb interaction at a couple of voxel clusters. So, I hope to perform pairwise comparisons to find out the detail. Any suggestion on how to do it?
Thanks!
