Hello Miguel,

There may be an issue with the version of python you are sourcing. The utility requires python 3.6+.

To check your version you can run: 'python --version'

If your version of python is not 3.6+ you will need to source an updated version of python.

External Email - Use Caution

Dear Freesurfer experts,

I am trying to use the aparcstats2table command (FSurfer V.6) in order to export the thickness measures but there should be an issue with my python version. This is the complete output:

aparcstats2table --hemi lh --subjects 4166 --meas thickness --parc aparc.a2009s --tablefile thickness.txt

Usage: python [options] python: error: no such option: --hemi

Could you give me some suggestions to solve this problem?

Thank you very much in advance.

Best regards, -- Miguel Ángel Rivas Fernández
