Hi Venkat,

the image looks ok, but it's hard to tell from a single slice or two and not being able to change the window levels. If you want to ftp a subject to us we're happy to take a look and let you know what we think.

Hi All,

I am working in ALS dementia patients where there is ventricle enlargement and more CSF filling when compared with controls. Since i am new to freesurfer and my knowledge of anatomy is limited i would like to clarify the following. Pial surface in right and left cerebral cortex looks suspicious to me, the brain extraction step left out some non brain regions, i tried to edit them but since some of the non brain regions are close to brain regions i didn't do too much editing for the fear of removing brain regions. I have attached a screen shot image in one of our subjects, kindly tell me whether the pial surface looks ok if not any suggestions to correct this problem.

Thanks in advance
