Dear All,
 
 
I'd like to average T1 anatomical images of all my subjects using spm8, but it's hard to find how to do this.
 
 
As some previous works indicated, I coregistered T1 anatomy images to individual subjects' mean EPI then normalised the T1 images but I couldn't understand how I could average these normalised anatomical images...
 
 
How can I do this and make average T1 image of all subjects? A little advice would be really appreciated.
 
 
 
Thanks a lot in advance & Best Regards.
