Small Update: Error Disappears if Using Freesurfer version 5.0 instead of 5.1. However, since I am keenly interested in the hippocampal-subfield segmentation capabilities of the most recent version, I am loathe to regress to an earlier version of FreeSurfer - Joshua Lee Graduate Student Center for Mind and Brain & Department of Psychology University of California, Davis 530.747.3805

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
