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 !
