[Freesurfer] TAL QA check failed

Experts,

I got the following error while running a subject with recon-all autorecon1

ERROR: Talairach QA check failed! z-score = -8 <= -4 = threshold Manual Talairach alignment may be necessary, or include the -notal-check flag to skip this test. See http://surfer.nmr.mgh.harvard.edu/fswiki/FsTutorial/Talairach Linux barnali-work 2.6.24-16-server #1 SMP Thu Apr 10 13:58:00 UTC 2008 i686 GNU/Linux

recon-all exited with ERRORS at Fri Jun 5 22:35:17 PDT 2009

I gathered from other posts on this error that the fix depends upon the z -score. In this case the z-score is -8, what is the best way to get it fixed. Previously i had fixed similar error and i had fixed it with tkregister2, but z-score was different

Thanks and Regards
