The arf3DS4 registration class contains information on the conversion matrices for brain registration purposes.
It is used to convert ARF models to standard space (MNI152), and to structural (T1) images. It is also used to look up the location of activated regions in standard atlases (Harvard-Oxford and Talairach).
The "registration" class is optional, for it to work properly a functioning installation of FSL is required.
