Hi,

 

I am running an analysis in a group of pediatric subjects (4-6 years old) and want to correct cortical thickness values by ICV before running the statistical model, since we have limited degrees of freedom. While I know this is not recommended for adults, I believe it is routinely done in pediatrics but I cannot find the implementation in freesurfer. Is there a straightforward way to normalize cortical thickness by ICV before running the glm?

 

Thanks,
