Hi haiteng,

Thanks for your reply, I will try to use SPM8 instead of SPM8b.

It's funny that you are also in Nanjing.

I used the dicom-import button and it provided the structure
information(hdr/img) for MRI button in 3D Source Reconstruction, but when
the process running there is need another 5 hdr/img files, and the process
output 5 nii files instead, so I think this is a bug. May be it has been
fixed in the lasted version, I will try it.

The goal of this reasearch is to provide assistance information for surgical
operation, so I need add the evoke response to indivial brain instead of
templete brain.

Then, do you know is there any SAM problem can co-operate with SPM ?

Best reagrds!
