Hi all,
I am trying to run 2x3 factorial model correcting for age, sex and intracranial volume. Just to give you insight in my data I have my fsgd file as

GroupDescriptorFile 1
Title DOSS analysis 2x3 factorial
Class MaleGroup1Low

Class MaleGroup1Medium

Class MaleGroup1High

Class MaleGroup2Low

Class MaleGroup2Medium

Class MaleGroup2High

Class FemaleGroup1Low

Class FemaleGroup1Medium

Class FemaleGroup1High

Class FemaleGroup2Low

Class FemaleGroup2Medium

Class FemaleGroup2High

Variables Age normVol

Input SUB001 MaleGroup1Low 18 0.4

And also my contrast files as

Group1Group2.mtx

[1 1 1 -1 -1 -1 1 1 1 -1 -1 -1]/3

MainEffectState.mtx

0.5 -0.5 0 0.5 -0.5 0 0.5 -0.5 0 0.5 -0.5 0

0 0.5 -0.5 0 0.5 -0.5 0 0.5 -0.5 0 0.5 -0.5

HighvLow.mtx

-0.5 0 0.5 -0.5 0 0.5 -0.5 0 0.5 -0.5 0 0.5

HighvMed.mtx

0 -0.5 0.5 0 -0.5 0.5 0 -0.5 0.5 0 -0.5 0.5

GroupxState-interaction.mtx

0.5 -0.5 0 -0.5 0 0.5 0.5 -0.5 0 -0.5 0 0.5

0.5 0 -0.5 -0.5 0 0.5 0.5 0 -0.5 -0.5 0 0.5

I'd appreciate if anyone could please let me know that my design is correct.

Thanks for help.
