<blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">Thanks Michael.  But is there a simpler method?  To be honest, I am not quite sure how to generate a transformation matrix to keep all the position &amp; orientation intact while changing the voxel sizes.  Is there no way to take some image, the new desired voxel size, and the interpolation method and then spit out a new image?<br>

Just do a reslice (spm_reslice).<br>

    Hi SPMers,<br>
<br>
    Does anyone know how to downsample images (ie go from 1.5x1.5x1.5<br>
    mm to<br>
    3x3x3 mm)?  I know SPM can downsample/upsample when running things<br>
    like<br>
    normalization or coregistration, but I can&#39;t figure out how to do this<br>
    outside of those functions.<br>
<br>
    Regards,<br>
