Good evening
in case you are still trying: here is an extract from a file I got from
Klaas that could explain and possibly help:

% Create 1st contrast for 'effects of interest'
        % (necessary because the current version of spm_spm returns an
        % empty array for SPM.xCon)

%------------------------------------------------------------------
        try
         iX0     = [SPM.xX.iB SPM.xX.iG];
        catch
         iX0     = [];
        end
        SPM.xCon        = spm_FcUtil('Set','effects of
interest','F','iX0',iX0,SPM.xX.xKXs);

So, put this "magic formula" to create sort of a dummy contrast and then
go on doing your own contrasts.

Hi Nicholas,

I'm pretty much guessing here, but I have exactly the same error as you.
The analysis worked when I tried it out on some dummy data, so it's not
the program for sure.  I think you might have an error in your contrast
specification - I for sure do, so that's what I'll be trying out, but
that will take me all night :(

Good luck with it,
Jane

Hi everyone.

I'm using a BATCH file to design, estimate and create contrasts for a
matrix that is modified from Karl Friston's spm_batch.m. The batch works
perfectly designing and estimating the matrix, but when it comes time to
create the contrasts for it, matlab spits out the following error:

??? Error using ==> spm_FcUtil
not contrast dim. in spm_FcUtil c

Error in ==> SavioTest at 516
SPM.xCon(end + 1) = spm_FcUtil('Set',cname, 'T', 'c',c(:),SPM.xX.xKXs);


I'm guessing it's something quite simple to fix, but I don't even know
where to begin. Any suggestion would be great.
