Hi,
While trying to add contrasts during 1st level analysis (in SPM8, using a Matlab script that closely follows one of Rik Henson's script), I'm getting the following warning:
"Warning:
c is not a proper contrast in +c->Tsp in spm_SpUtil
!!! projecting... "
when I call
spm_FcUtil('Set',cnam{c},ctyp{c},'c',cw,SPM.xX.xKXs)
where I've specified my contrasts in the following manner
cnam{1} = 'A > B';
cwgt{1} = [kron([-1 1 2 0 0 0 0 0 0],1) zeros(1,numOfNuisanceRegrs)];
ctyp{1} = 'T';
and padded cwgt with a zero for the constant
SPM.xVol.R has no NaN's....
What am I doing wrong?
Thanks for any pointers!
