We find that it helps to make the calcarine cut go very far posterior, usually requiring you to rotate the brain by about 30 degrees so you can actually reach the occipital pole. Then for the cutting plane points we use the anterior point of the calcarine cut, the acsending limb of the cingulate sulcus, and on the lateral side, we use the asecding part of the slyvian fissure. Sometimes this will still result in horns or weird things on the patch. I haven't had much luck in trying to get rid of those things.

Hi all,
The freesurfer manual on occipital cuts is clear on where to cut, but does anyone have experience on where to cut, so that the flattening of the cut would look reasonable and consistent? I've tried several cuts, but whenever I tried it, the flattened surfaces look different and it is not similar to the flattened surface that we see in textbooks.
If anyone has an experience on occipital cuts, please give me some advice.
Thanks. Nam. _______________________________________________ Freesurfer mailing list Freesurfer@nmr.mgh.harvard.edu https://mail.nmr.mgh.harvard.edu/mailman/listinfo/freesurfer
