Hi everyone,

I need to draw Heschl gyri on freesurfer pial surface of my subjects but it’s not easy because this area is not directly visible. So:

1. Is there a simple mean to cut the surface to see more internal areas with freesurfer tools (or other???) ?

2. Is it possible to extract only desired areas from the “aparc.annot.a2005s” files and how to modify them manually?

Thanks
