Dear Freesurfer list, I am using Freesurfer 6.0 in Ubuntu 16.04. In the troubleshooting I have encountered a frequent problem with many of my subjects. I enclose an example. Is it necessary to edit the areas that have not been included in the wm mask? Namely, that tiny area close to the temporal horn of the left lateral ventricle (Image_1)? As you can see in the other image (Image_2) this might be affecting the pial surface that seems to include parts of wm in the vicinity of the temporal horn. How would you deal with this?
Best wishes, Manuel
Hi Manuel
I think the area you are talking about is in the hippocampus, no? In which case it is not neocortex and you don't have to worry about it.

OK, indeed it is in close relation with the hippocampus. Thank you.
Could anybody check now the enclosed image in which the right occipital horn has not been filled? How to proceed with this?
Regards,
Manuel
