Hi,
I'm having some problems using the talairach command on scewed T1 volumes (the subject has been scewedly scanned). The talairach coordinates (mni Talairach) does not seem to transform the volume properly, resulting in scewed segmentations when I manually insert the mni Talairach coordinates into the mri_filled command. (that is, mni Talairach coordinates for lh, rh, c.callossum and pons).
Are there any alternative transformation commands which may solve this issue?
Best wishes,
Lars Tjelta Westlye
I think you can use the register tool distributed by the MNI to manually specify the talairach transform.
cheers, Bruce

You can also use tkregister2 to visually checked and edit the registration. Something like:
tkregister2 --s subjectid --fstal
You can run
tkregister2 --help
to get docs on how to use it.
