Hello FS experts,
I have a question about setting the following contrast in mri_glmfit
My contrast of interest:
Does area.pial --age correlation, accounting for gender, differ between PT and HC?

Class Female_PT
Class Female_HC
Class Male_PT
Class Male_HC
If I set my classes are as above, should my contrast be the following:

fem_PT, fem_HC, male_PT, male_HC, age
1 -1 1 -1 0

Thanks
Pablo
