Dear Marko Wilke and SPMers：
The activation map overlaid on the T1 image very well after the T1 image was
normalized using the seg_sn.mat file. Thank you!
The following question is: Must I follow the steps in the SPM5 Manual(Session VI
Chapter 25) if I want to overlay the activation map overlaid on the same one's T1
image? Is there any other way to get seg_sn.mat file besides segmenting the T1 image?
I found that a _sn.mat file would be got after normalize
the fMRI data(estimate and write, the steps as below). Can I use the _sn.mat
file to write the T1 image?
- realign the fMRI data
- normalize(estimate and write) the fMRI data: source image is the mean
image(mean01.img and mean01.hdr) got from the realign step, images to
write are the realigned fMRI data, the template image is the EPI.nii in the
SPM5's template directory.
- write the T1 image using the mean01_sn.mat file
