Dear all, I've been having problems with spm99 in spatial normalization. I used the mean image from the realignment and the EPI template in spm99 for the normalization. However, the normalized images were substantially larger than the template, most obviously in the sagittal and axial views. Strangely, this problem occurred only for the scans of a few subjects. Others were fine. And, it's always the frontal region that was stretched beyond the bounding-box. I check the header. It look fine. I also tried adjusting the origins for those images. It still didn't work. But, when I used spm96 with the same procedure, the normalized images looked fine. I'd greatly appreciate it if anyone can point out to me what might be the problem.
