AI,

You can try to resample both of your volumes to the same reference
before extracting subvolumes. To do this, you can use "Resample
Scalar/Vector/DWI Volume" module:

http://wiki.slicer.org/slicerWiki/index.php/Modules:ResampleScalarVectorDWIVolume-Documentation-3.6

As I suggested earlier, you might be able to receive a quicker and a
more complete answer to your questions if you post to slicer-users
list.
