Hi,
I am trying to run freesurfer on some SPGR sequences that I have on a few subjects. I managed to import and convert the DICOM files to .mgz with success, but when I ran the skull strip I have a significant amount of skull left in some places and a large chunk of brain missing in other planes on the same brain. I am wondering if there is a problem with intensity normalization (most of my brain appears to be close to an intensity of 110), but I do not know how to fix the problem. Can anybody offer some suggestions on how to fix the problem?
Thanks.
Sincerely, Ben Wilson
