Hi,
in the design matrix you demean the covariates
with the -D you demean the data in your images

>> Medicine.
>>
>> We are currently recruiting a post-doctoral fellow interested in
>> carrying out combined fMRI/DTI/structural MRI studies as part of a

>> broad spectrum of approaches.
>>
>> The neuroimaging studies will be conducted at the Gruss Magnetic
>> Resonance Research Center (MRRC), a 19,000-square-foot facility on the
>> main (Resnick) campus of the Albert Einstein College of Medicine of
>> Yeshiva University. The MRRC has the most state-of-the-art imaging

>>
>> Candidates are sought with a doctorate in engineering, computer
>> science, mathematics, neuroscience, or related fields, research
>> experience in neuroimaging (fMRI/DTI/structural MRI), programming
>> skills in MatLab, C/C++, and working knowledge of UNIX/LINUX
