Dear. MNE users.

I have a question regarding talairach transform failure.

When I run 'mne\_setup\_mri --subject $SUBJECT --overwrite',  
it says adding talairach transforms failed and talairach transforms will  
not be included into the output file, which is COR.fif.

In addition, when I run 'mne\_analyze' and load surface, it again says  
adding talairach transforms failed.

To solve this issue (as MNE users have advised before), I have run,

mri\_add\_xform\_to\_header -c \  
$SUBJECTS\_DIR/$SUBJECT/mri/transforms/talairach.xfm \  
$SUBJECTS\_DIR/$SUBJECT/mri/T1.mgz \  
$SUBJECTS\_DIR/$SUBJECT/mri/T1.mgz

This actually solved the failure issue with mne\_analyze, but not the  
failure issue with mne\_setup\_mri. (why???)

So I'm now wondering whether the COR.fif which does not include talairach  
transforms will be problematic when running mne\_watershed\_bem and  
forward/inverse solution..

If not, I can ignore the talairach transform failure in COR.fif and move on  
to the next step with COR-'whoami'\*.fif that I made. This COR-'whoami'\*.fif  
has talairach transforms since I've run the mri\_add\_xform\_to\_header...

Is there anyone who can give me some advice?

I appreciate it in advance!

Best,  
Ji Won Bang
