Hi Sameer,

I don't think it'll affect your results, but before you rerun recon-all with -notal-check flag, check the registration in tkregister2 and make sure it's correct.

hi all, I ran recon-all on a case, and it exited with errors, and the error message looks like this:

ERROR: Talairach QA check failed! z-score = -6 <= -6 = threshold 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.

will there be a difference in the results if i use that flag to skip the test?

Thanks, Regards, Sameer
