Hi Carles,
c = [-1 1 0 0 0 0 0 0 0 0 0 0];
cname = 'fase1-basal';
SPM.xCon(end + 1) = spm_FcUtil('Set',cname,'T','c',c(:),SPM.xX.xKXs);
sounds good to me :-)
1st make sure that c as all the columns of your design matrix including
the cste term, meaning that here you should have 5 conditions + 6 motion
regressors + cste ??
2nd and unfortunately i still didn't find how to solve it, if you run
spm_FcUtil whereas no contrast has been estimated yet, the SPM.mat
structure isn't updated and that's why it crashes ; by default I did a
all vs rest for my subjects then ran the contrast batch with spm_FcUtil
maybe someone out there knows how to update the SPM.mat when no contrast
has been performed ??
Best
Cyril
