Hi all,
Just to say I haven't solved the problem yet but have just proceeded testing for "simple effects" (for the effect of one var within the levels of the other). So my results make sense no matter how many/which interactions were significant.
Even so, it would still be good to know what I was doing wrong in doing an F-test for all interactions. So far the logic of FSL has always been very clear to me, often even intuitive, so i'm simply curious about the logic behind this problem. Hence this reminder of my post.
I previously uploaded the input files and a text file with the command I used (reference number 958045). Please do let me know if you need the data files too.
Best wishes,
Emma
