Dear Free Surfer team and Bruce,
I have been doing well editing the skull stripping, and using control points to improve white matter segmentation. Furthermore, the few participants I had problems with due to large ventricles were solved using the flag you recommended me to use. I am very grateful for all your help.
However, I am facing another problem I thought I could solve using control points as well but this is worsening things instead of improving them. I refer to grey matter segmentation. I have found that several participants, more than I would like, are having problems with grey matter segmentation in the ventral temporal lobes and in the occipital lobe as well.
I wonder if you could kindly help me with this, telling me how I could solve this problem so GM and WM segmentation are fine.
Yours sincerely, Rosalia
Hi Rosalia
if you upload an example with voxel coordinates of where you see problems we will take a look

Hi Bruce,
Thank you for your reply. I am sending now a file called 013.tar.gz via ftp. And this is not the worst...there are other with more regions that have not been considered in the segmentation process. I would like to know how could I cope with GM editions, as I am doing with control points with WM.
Yours sincerely, Rosalia
