On the tutorial it states that it is not possible to directly edit the location of a surface. However, on the corresponding video posted onto the website the gentleman mentions being able to accomplish this. I have been trying to locate the literature on how to do this and have not been successful. I am using 'freesurfer-Darwin-OSX-stable-pub-v6.0.0-2beb96c'

I would kindly appreciate some help on locating any tutorials or information available.

Thank you for your help.
