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.

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!

I mean to just load the orig.mgz into tkmedit and
see if it is oriented 
correctly. Assuming that it is oriented correctly,
then it sounds like 
the talairach transform is messed up pretty badly.
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.

transform..i checked brainmask.img and T1.img after
loading the transform and they had this

problem..The

header and geometry info look fine..

No, It has the same problem in tkmedit too.
