Dear Dr.Griffanti,
Hi,
I have the design matrix used for dual regression, designed with GLM . Within there are 2 contrasts: Autism>Controls & Controls>Autism.
The problem is: I have just (dr_stage3_ic00??_tfce_corrp_tstat1.nii.gz) but there is no (tstat2.nii.gz).
In GLM, I set the number of EVs to 2. Then I set the EV1 as Controls and EV2 as Autism. In "contrast & F-tests" window the contrasts number has set to 2 and C1:(Controls>Autism) & C2:(Autism>Controls). These were the specification of ".mat" and ".con" files I've used in dual regression code.
Am I supposed to have ".mat" and ".con" files separately for C1 & C2 ( run GLM twice) to use for dual regression?
Do you have any idea what might be wrong with my procedure?
Thanks a lot for your useful answers.
Javanray.
