Hi SPM list:
Related to this issue, we have a subject who moved between the anatomical images and the first and second fMRI runs. When we reorient, realign, and normalize EPI images to the T1-anatomical images, the result is obviously wrong, and we get a shifted map of activation, where areas are not correctly located.
We have tried to solve this problem by reorienting, realigning, and just normalizing EPI images to themselves. However, we seem to get a rather similar, unsatisfactory result.
Is there any better way to deal with this?
Many thanks once more,

Asunto: movement between runs
I have a subject that has moved between run1 and run2. With individual
analysis, does spm consider each run as a separate session or all runs as
one session? How does spm deal with movement between runs?
