Dear SPM experts,

I have sagittal T1w and T2w images with slight differences in voxel size
and matrix size (smaller voxel and higher matriz size in T2 images). In
order to improve the segmentation accuracy I would like to perform a
multi-spectral classification with two channels (one per modality). Since
T2 images have slilght differences in some acquisition parameters respect
to T1, is necessary to do some previous transformation in T2 images before
do the segmentation in SPM?

Thanks in advance.

Best regards,
