Dear FSL expert,
I want to compare the FA map between patients and healthy controls. Patients have scanned 2 times, once before their treatment and another after 3 months. Could you please help me verify if the design below is correct?
EB EV1 EV2 EV3 EV4 EV5 EV6 EV7
1 1 0 0 1 0 0 -12,64
1 1 0 0 0 1 0 10,36
1 1 0 0 0 0 1 22,36
1 0 1 0 1 0 0 -16,64
1 0 1 0 0 1 0 -11,64
1 0 1 0 0 0 1 -7,64
1 0 0 1 0 0 0 2,36
1 0 0 1 0 0 0 -2,64
1 0 0 1 0 0 0 13,36
1 0 0 1 0 0 0 10,36
1 0 0 1 0 0 0 -7,64
EV1: patient time scan 1.
EV2: patient time scan 2.
EV3: HC's data.
EV4-6: subject mean.
EV7: covariate (demeaned whole group).
and the contrasts are:
Difference Pt1-C 1 0 -1 0 0 0 0
Difference Pt2-C 0 1 -1 0 0 0 0
Difference Pt1-Pt2 1 -1 0 0 0 0 0
I really appriciate any help you can provide,
Best regard,
Kim TD
