do you want to upload one of them for us to look at? On Wed, 16 Jul 2008, Vina Goghari wrote:
I would say it's pretty typical. I tried a random set of 4 subjects of the ~70 and I get the same error and similar mis-alignment between talairach and original.
Any thoughts?
Thanks, Vina

That would just do the conversion, it won't fix the problem. Does this happen with all your subjects? How is the quality of your T1s (the one you sent looks a little funny).

I know someone that uses something like what is below to avoid using tkregister: mri_convert $subject/mri/T1.mgz $subject/mri/T1.mnc mritotal -protocol icbm $subject/mri/T1.mnc $subject/mri/T1.xfm mv $subject/mri/transforms/talairach.xfm $subject/mri/transforms/oldtalairach.xfm cp $subject/mri/T1.xfm $1/mri/transforms/talairach.xfm
Doug and Nick can correct me if this isn't a good idea. You can do: mritotal -help to learn more about it. Allison

Thanks Nick. I was wondering whether since this is a problem for all my subjects (n=70) is there anything else that could fix the problem (i.e. setting some parameter differently etc), so I wouldn't have to do it manually for every subject?

Vina,
See this page: https://surfer.nmr.mgh.harvard.edu/fswiki/FsTutorial/Talairach
(you won't need the tutorial data, just use your subject)

So I viewed the talairach transform using tkregister2 and this is what I see for target and moveable. How would I go about fixing something like this:
See attached images.
