Thank you for the prompt response.
I tried what your suggested. However, the new batch file can not be read by spm anymore. The error massage showed "a href=matlab: opentoline[cfg_util, 648, 0,">cfg util at 648" in a pop-out window and "Load failed: 'D:\NeuroSpin\number_syntax\fmri\sub03_ma110333\1stlevel\no_mor\1stlevel_2.mat" in matlab. Anyone has any idea about what it is wrong?
