whether the FWHM is default as 8*8*8 when using DPABI for VBM analysis?

 Dear Yan,
       I am sorry to trouble you. May I ask you whether the FWHM is default as 8*8*8 when using DPABI for VBM analysis? I don't know whether I will changed the FWHM from default of 4*4*4 into 8*8*8? 
Thanks.
Your sincerely,
Xijian
