Hi Michael, please find the .png and .fsf files attached. The content of the gfeat/cope2 (and all subsequent copes) is a log folder, a stats folder, design files, report files, example_func, mean_func, and a mask. In the stats folder, there is only a log and a DoF file. Given that you picked up my initial question, I assume that you generally agree with the procedure that I suggested (to use zstats maps from the second level feat as randomise inputs for a 2x2 ANOVA). I am asking because the contrast set up in FSL is a little confusing for me. I am a BrainVoyager turned FSL user and am used to set up all contrasts on the group level. So the fact that I am setting up contrasts on the level of individual runs is strange to me. I know how to use randomise to set up the ANOVA that I want to do and therefore planned my analysis this way. But if you think that I should do this differently (i.e., set up the ANOVA as a higher level feat) please let me know.
