#@# Talairach Failure Detection Wed Nov  2 02:03:32 EDT 2011<br>/home/virtualuser/freesurfer/subjects/test005/mri<br><br> talairach_afd -T 0.005 -xfm transforms/talairach.xfm <br><br>I am receiving the error (pasted below) on about half of my scans, despite all cans using same protocol. I detect no obvious issue with the quality of the images. I have original dicoms, and am using mri_convert to save into a single .mgz (or .nii, doesn&#39;t neem to make a difference), and the unpredictability of the error makes diagnosis problematic. TKMedit2 reveals absolutely wacky registrations. I am processing on Freesurfer 5.1, and have replicated issue on two different installations. I am designing a new longitudinal study inheriting the same imaging protocol and I do not want to get in a situation demanding manual editing of the talairach. Can anyone help me out? Thanks, Joshua<br>
