I am sorry to interrupt. I am working on VBM and use SPM5 to perform normalisation and etc. I am just wondering what variable in "job" should I modify to add it more source image files or change the source file image file and template file? Similar question also goes for images for statistical analysis in 2nd level specification.

Dear Tao,

There is no "Multiple Contrasts" option like with "Multiple Conditions" or "Multiple Regressors" but this can easily be done with a script:

% Define as many T-contrasts as you want
contrasts(1).name = 'Name_Contrast_1';
contrasts(1).convec = [1 0];
contrasts(2).name = 'Name_Contrast_2';
contrasts(2).convec = [0 1];

% Specify and estimate new T-contrasts
spm('Defaults','fMRI');
clear jobs
jobs{1}.stats{1}.con.spmmat = cellstr('/path/to/SPM.mat');
for i=1:length(contrasts)
jobs{1}.stats{1}.con.consess{i}.tcon = contrasts(i);
end
spm_jobman('run',jobs);

I hope this helps,
Guillaume.

Dear SPM5 users,

I would like to know whether there is a method to enter the several T tests contrasts at the same time, a little like to enter multiconditions ?
thank you for your help !
