Feng-Xian,

I assume you've created .label files for your ROI's? If so, then you can open the .label file in a text editor and the vertex numbers will be the first number in each row (followed by x,y,z and a possible stat value, usually 0).

Hi,

I know Freesurfer has a function which can label ROI by us. But, I want to know how many vertices do the labeled ROI has.

Would you teach me how to obtain the vertex of the labeled ROI ?

Thank you in advance!

Feng-Xian
