RE: Three-way ANOVA
Hi Jimmy,
Please take a look at the reference manual and FSL GLM wiki for a variety of common design matrices:
https://fsl.fmrib.ox.ac.uk/fsl/fslwiki/G...
Previous posts on this forum also provide templates for design matrices.
I suggest beginning with a 2 x 2 design in the first instance. Interpreting 3rd and 4th order interactions can be difficult.

Thank you, Andrew. What should my design matrix
look like?
I have 50 subjects. is it like 50x3 double? So the first column is either 0 or 1 (group0/group1), second column is 1 or 2 (stimulus 1/stimulus 2) and third column is any number between 1-80 (time sample 1: time sample 80).
And my connectivity matrix will be 90x90x80x50? 90 is the number of nodes.
Thank you so much.
