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!

Dear yinfei:
   You could ty the latest verision instead of  spm8b, for there may be some bug in the beta version. Currently , I am using spm8 to analysis  MEG ,and  everything goes well. You can get the individual  MRI hdr/img  file through the spm8 button  dicom import   and  then import  this MRI image into co-register step  in the 3D source reconstruction procedure. 
   As far as l know ,SPM8 normalizes the individual MRI image  matching with a brain  template  in order to get statistic significance. This is also explainable. You can obtian the evoked response or the induced response (not evoked brain)in the subsequent choice at the invert opinion.
 Hope this helps.
best,
Haiteng

Hi, I am trying to use SPM8b to analyze MEG data in matlab,
after convert and some pre-process, I start to 3D Source Reconstruction.

I loaded my data.mat file first, and then clicked the MRI button, 
after import the DICOM data, the process start to registering, and then a mistake happened.

Error using ==> spm_vol>subfunc at 111
File "/home/loveplay/Desktop/fMRI/MEG238/PATIENT
(G)/c1s104384-0002-00000-000001-01.img" does not exist.

I went to the path,
The folder doesn't have img file but there is a nii file.

I try to convert the nii file to hdr/img file by MRICron and repeat the operations, the programe is OK.

But I think this is not a good method because I should repeat this operation every time when I want to analyze the data, it's clear that the SPM make a mistake  output the nii file instead of the img/hdr files, so I hope to repair this bug, I hope somebody can tell me the function output this file, or the function can convert nii to img/hdr, thank you very much.

** There is another problem is that I found that spm/meg add the evoke area to templete brain, but I want to add the area to indivial brain, could you tell me  what should I do, thank you again.

I am sorry for my suck English, I hope you can understand me.
