is it a requirement that all data from multiple subjects hav the same voxel
sizes when running spm_sn3d?
I have many subjects, each with multiple scans; I have a mean image from
spm_realign for each set. so, voxel sizes within subjects are uniform, but
not *across* subjects [the diffs are small, but non-zero].
I can run spatial norm for any one subject, but as soon as I try to run
multiuple subj, I get "not enough overlap" after an attempt at the affine
step of the ?first subject.
running spatial norm with SPM96 [embedded in MEDx], I had no problem with
this type of data.
hope you can help--
thanks
