Select Make Occip Surface Cuts from the Subject Tools menu in csurf: (fig1) attachment:fig1.jpg
1. Make calcarine sulcus relaxation cut. · Select points (left-click) along the calcarine fissure beginning at the occipital pole and moving anteriorly. · Open-line cut with CUTLINE (surfer tools). (fig2) attachment:fig2.jpg
2. Specify cutting plane. · Select three points (labeled 1, 2, and 3 below) to define the cutting plane, and a fourth point (labeled 4 below) to specify which portion of the surface to keep (left-click). (fig3) attachment:fig3.jpg
3. Make the planar cut. · CUTPLANE button. (fig4) attachment:fig4.jpg
4. Save patch. · Specify the patch name in the patch field and press WRITE. The default names for the occiput cortical surfaces are: rh.occip.patch.3d lh.occip.patch.3d
