Pictures for checking normalization not created

Dear all,

Thanks for your nice softwares. I am using DPARSF. I can't have the pictures for checking normalization. Insted, I have got a warning.txt file that says : "Since Image Processing Toolbox of MATLAB is not valid, the pictures for checking normalization will not be generated.\n"

Does it mean that I need this Toolbox of MATLAB to have pictures for checking normalization ??
