Victor, upsampling your data will probably not help you do your subcortical segmentation and will only make things take longer/require more memory. If you really want to do it, check out the documentation for flirt. You can use flirt with -applyisoxfm. or use -applyxfm with a -ref volume in your desired resolution and coordinate space.
