Hi Corey,

if the talairach transform has been computed (as it is in recon-all), then loading one of the standard anatomicals will bring it up. Something like:

tkmedit <subject> norm.mgz lh.pial -aux ct.anat.nii

where <subject> is the name you gave to recon-all .

cheers, Bruce

Hi Freesurfers,

We have an MRI coregistered with a CT scan using spmregister. I have converted the CT to the anatomical volume using mri_vol2vol. We are then trying to view the anatomical ct in tkmedit and output talairach coordinates but as of now can only see RAS coordinates. Is there a way to either view the talairach coordinates or to transform the RAS to talairach coordinates? The former would be ideal.

tkmedit -SUBJECT ct.anat.nii lh.pial

Thanks.

Best, Corey
