Hello FreeSurfer Support,

I reached out the other day about if there was a way to specify the data is from a specific gender or age during the recon all code, such as a tag at the end. I was told that there is not way to tell recon-all about demographics/subject meta data, and not to worry about this during recon-all, but instead add age and gender as covariates in the model later.

Does this mean FreeSurfer automatically finds the right regions regardless of age or gender? Does this work based on gray/white matter thresholds or something similar, so regardless of the demographics of the brain, it find the right regions? Thank you for your time.

Best,
