How to obtain the average sulcus

[Luna Wang]

Hi!
I want to creat an average sulsi of some sulcus and parameterize it. I have found a tool called "Crotical Surface →sulci-stats→Average Sulci". Can it realize my thought?? What is more, I don't know how to use it. I have tried sevral times, but I failed. So Could you teach me how to use the "Average Sulci
I am looking forward your reply!!
Thank you very much!
