Hello SPM'ers,
I'm running an fMRI multiple regression analysis with VBM data. I have 1
group(15subjects) ,images from 3 time points(T0 T10 T60) and one score for
each time point(45 scores).
I would like to look at:
+ve correlation of the score with for example: T0>T60 .
Would I enter all the images in order of Time then assign 6 covariates:
1 group T0[1*15 0*30]
2 group T10[0*15 ,1*15,0*15]
3 groupT60 [0*30, 1*15]
4 score group 1 [15 scores @ T0, 0*30]
5 score group 2 [0*15 ,15 scores @ T10, 0*15]
6 score group 3[0*30,15 scores @ T60]
Would the contrast for
+ve correlation of the score with T0>T60 be [10-1101] or [10-1111]
Advice is greatly appreciated.
Thanks,
Maria
