It sounds like you're on top of the more advanced FLIRT options
needed to get reasonable registrations. I think your question is how
to use these settings in the context of FEAT registration.
The easiest thing to do would be to run the normal FEAT
registrations, and then go into the .feat/reg directory and overwrite
the example_func2highres.mat highres2standard.mat and
example_func2standard.mat files with the correct matrices found
outside of FEAT.
Cheers, Steve.
