I wonder whether there is a way to convert surfaces back to the subject native space. Thanks!

Yes,It is perfectly fine with the --regheader optionmwhich means no problem with geometry info. But how do I fix the talairach.xfm?
Thanks a lot!

When you run tkregister2, try adding --regheader. This will ignore the info in the talairaach.xfm file and force it to use the geometry info. it will likely be very far off, but the basic orientation should be ok.

Thanks in advance Regards,

You can start with that one and fix it by hand (which is a hassle). We are working on ways to make the talairach more robust. BTW, if you run tkregister2 again after fixing it, you should not include the --regheader as that will ignore your previous edits.
