[Freesurfer] failed Talairach quality check; alternatives?

Hi all,

I have an MPRAGE which consistently fails the Talairach quality check (see attached error) in autorecon1. (A 32-channel coil was used in this scan, and I suspect that might be a cause of the failure.) Per the wiki's suggestion, I have tried to manually fix the transform in tkregister2 and rerun reconstruction, but despite multiple attempts, I haven't been able to get a transform which satisfies the quality check. From similar list posts, I thought it might be possible for me to Talairach in an external program (BET, AFNI, etc.) and create a transform file that FreeSurfer can read. If this is possible, could you give me an overview of the process, or point me to existing documentation?

Thanks,

Jeff Phillips
