#@# Talairach Failure Detection Wed Nov 2 02:03:32 EDT 2011 /home/virtualuser/freesurfer/subjects/test005/mri
talairach_afd -T 0.005 -xfm transforms/talairach.xfm 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'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 ERROR: talairach_afd: Talairach Transform: transforms/talairach.xfm ***FAILED*** (p=0.0030, pval=0.0000 < threshold=0.0050) Manual Talairach alignment may be necessary, or include the -notal-check flag to skip this test, making sure the -notal-check flag follows -all or -autorecon1 in the command string.
