When I compare headers, these are the differences:

Before 3dAllineate

name offset nvals values
------------------- ------ ----- ------
intent_code 68 1 1005
datatype 70 1 64
bitpix 72 1 64

after 3DAllineate

name offset nvals values
------------------- ------ ----- ------
intent_code 68 1 0
datatype 70 1 16
bitpix 72 1 32

The dimensionality is the same, the transformation has been applied, but the datatype has changed. Can I prevent 3dAllineate from doing that?
