Dear SPM experts I tried to do an paired t-test with SPM5 (Upd 1782), but the following error occurred: Error running job: Output argument "V" (and maybe others) not assigned during call to "/Applications/MATLAB74/work/spm5_upd1782/spm_reml.m (spm_reml)". In file "/Applications/MATLAB74/work/spm5_upd1782/spm_spm.m" (v946), function "spm_spm" at line 907. In file "/Applications/MATLAB74/work/spm5_upd1782/spm_config_fmri_est.m" (v832), function "run_est" at line 394. What does it mean?
