Dear FSL-Experts,
I'm trying to conduct a paired t-test with a covariate on my longitudinal VBM data. I have 12 subjects and in the last column is the demeaned covariate.
1 1 0 0 0 0 0 0 0 0 0 0 0 -12.79
1 0 1 0 0 0 0 0 0 0 0 0 0 -14.45
1 0 0 1 0 0 0 0 0 0 0 0 0 -19.12
1 0 0 0 1 0 0 0 0 0 0 0 0 -12.12
1 0 0 0 0 1 0 0 0 0 0 0 0 7.71
1 0 0 0 0 0 1 0 0 0 0 0 0 20.71
1 0 0 0 0 0 0 1 0 0 0 0 0 18.55
1 0 0 0 0 0 0 0 1 0 0 0 0 1.21
1 0 0 0 0 0 0 0 0 1 0 0 0 17.21
1 0 0 0 0 0 0 0 0 0 1 0 0 -9.54
1 0 0 0 0 0 0 0 0 0 0 1 0 -18.12
1 0 0 0 0 0 0 0 0 0 0 0 1 20.71
-1 1 0 0 0 0 0 0 0 0 0 0 0 -12.79
-1 0 1 0 0 0 0 0 0 0 0 0 0 -14.45
-1 0 0 1 0 0 0 0 0 0 0 0 0 -19.12
-1 0 0 0 1 0 0 0 0 0 0 0 0 -12.12
-1 0 0 0 0 1 0 0 0 0 0 0 0 7.71
-1 0 0 0 0 0 1 0 0 0 0 0 0 20.71
-1 0 0 0 0 0 0 1 0 0 0 0 0 18.55
-1 0 0 0 0 0 0 0 1 0 0 0 0 1.21
-1 0 0 0 0 0 0 0 0 1 0 0 0 17.21
-1 0 0 0 0 0 0 0 0 0 1 0 0 -9.54
-1 0 0 0 0 0 0 0 0 0 0 1 0 -18.12
-1 0 0 0 0 0 0 0 0 0 0 0 1 20.71
Contrasts:
A 1000000000000 (first time point)
B -1000000000000 (second time point)
C 0000000000001 (cov)
Here is my randomise command:
randomise -i GM_mod_merg_s2 -o GM_mod_merg_s2 -m min_mask_GM.nii.gz -d paired_t-test.mat -t paired_t-test.con -e paired_t-test.grp -n 5000 -T -V -D
Is this design correct?
Thanks in advance for your help.
Anna
