Thanks Volkmar and John, that's the tool I need. I can use Composition with Deformation Field and Identity to select the different resolution of anatomical and functional images. But first I need to create a template image for each desired resolution. Is it possible to define the parameter (voxelsize, bounding box) like in normalise write? Or is it too difficult to include this option? Best regards, Michael.
