Hi Freesurfer Team,

No worries, I have found a helpful solution from an old thread using mris_expand. http://www.mail-archive.com/freesurfer@nmr.mgh.harvard.edu/msg40894.html

Hi Freesurfer Team,

Is there a way to visualise the sampling edges across a range of projfrac values (0.1 (closer to WM) - 0.5) and overlay them onto PET data?

Any suggestions are greatly appreciated. Thanks.

Best Wishes, Elijah
