I am using 3dWarp to oblique my anatomical dataset. In doing so, the warped anatomical dataset doesn't seems to capture the entire anatomy. Instead, the first couple of slices are being cut off and there are extra slices at the end. The voxel dimensions are the same in warped as in original dataset. Brain volume has increased.
3dWarp -card2oblique epi+orig -prefix anat_obl+orig -gridset anat+orig anat+orig
How can I fix this?
