External Email - Use Caution

Hi all, I have been trying to create a flat patch of occipital cortex using the following tutorial (https://secure-web.cisco.com/18Kww5tnkyQOlM1ft0T_n7raXdSOUfLM9sJBa4TZ-zMjq2d...). I have tried following the instructions in Freeview and am able to create a cut down the calcarine sulcus, but cannot find the “cut plane” button described. I was wondering whether this is implemented in Freeview, or whether this tool is only available in tksurfer?

Freesurfer Version: 7.1.1 OS: Mac OS, Monterey 12.2.1

Many thanks! Brandon
