I am trying to reconstruct some 7T images but they repeatedly fail Talairach step
The tkmedit displays normal coronal, sagittal positions for the target.
If I use tkregister2 the moveable appears odd – please see the attached

The error message is


#@# Talairach Failure Detection Thu Jul  8 10:58:38 BST 2010

ERROR: talairach_afd: Talairach Transform: transforms/talairach.xfm ***FAILED*** (p=0.0000, pval=0.0000 < threshold=0.0050)


The talairach.xfm shows

What should I do next?
Thanks
