Dear FreeSurfer experts,

I did contact you before regarding the problem below ( Talairach Failure Detection ) and one suggestion was to use lower resolution MPRAGE rather than using .5mm one. ( Our MPRAGEs were acquired at 7T scanner with 0.5mm isotropic resolution). I acquired a new MPRAGE at 7T scanner with 0.8mm isotropic resolution but unfortunately it failed again.

( Note, regarding the inhomogeniety, I used SPM5 for normalization. Furthermore, I tried also using flag '-notal-check' once but did not work)

Any other suggestions I can try, Please?
