Hi Nick and all: The talairach_avi can work on my data. In my mind, modifying talairach registration manually should affect the value of talAviQA and z-score. So when we rerun autorecon1, it will give us new talAviQA and z-score, but it outputed the same talAviQA and z-score on my data .This is very confusing. What is problem?

Zonglei Zhen,

What is the age range of your subjects?

You can add -notal-check to the end of the recon-all string to skip the check. We have seen some problems with the talairach_avi processing on some young adult populations though.

Hi all: After autorecon1 was done, I corrected the talairach registration manually. Next, I rerun autorecon1 on the data, but tal_check still gave the same talAviQA and z-score as non-corrected. What's the problem? Is it necessary to rerun autorecon1? Can we skip autorecon1 and do autorecon2 directly?

My version is FreeSurfer4.3.

Thanks.
