Hello FreeSurfer Users,
I looked for a possible solution to my problem in the Mail Archive and found this article referring to almost the exact same problem I am having: http://www.mail-archive.com/freesurfer@nmr.mgh.harvard.edu/msg06314.html. Basically, pieces of the subarachnoid space/pia mater/arachnoid/dura mater/skull are being segmented as the cortex in certain slices and this occurs when it is physically adjacent to the gray matter. Besides this point everything else seems to be running smooth. In the related article I found that this may be caused by the MR parameters so I will give you the acquisition information that I know. The acquisitions are SPGRs, taken on either a GE 3T or 1.5T and the resolution is 1mm isotropic. Any solutions besides going through each series slice by slice and making corrections would be greatly appreciated. Thanks, Cyrus ********************************************************** Electronic Mail is not secure, may not be read every day, and should not be used for urgent or sensitive issues
