HI Mic,

Terribly sorry for not seeing this earlier.

You can use infantFS for the 2-4.5 year age range. I would only start using the adult version over that age limit and for several years I would still carefully look at the outputs. We wrote up an editing guideline for the 4-6 year age range that you mind find handy:

Subject: [Freesurfer] Use of infantFS and FS in the interval 2 - 4.5 years of age

External Email - Use Caution

Dear FS experts,

I see it is recommended to use infantFS below 2 years of age, whereas FS has been used for 4.5 years and above.
I was wondering what could be used in the interval 2 - 4.5 years of age: which are benefits and drawbacks of both?

Thanks, appreciated,

Mic
