SPMer's,
I have a question concerning the re-aligment step. If I am running a multi-subject fMRI study and want to re-align each subject's scan immediately after it is acquired, how can I ensure that the re-aligned scans will have the same voxel dimensions? I just separately re-aligned the scans from 5 different subjects and the resulting re-aligned images for each subject had different voxel dimensions (different Z dimensions to be exact) Is there a way to use the re-alignemnt parameters from the first subject to use on all subsequent subjectsto ensure that the voxel dimesions are the same for each subject? Or must I re-align all subjects at once?
