yes ..the registration is nicely aligned and i did check the green-lines alignment in tkregister2
is their any other reason for it showing segmentation fault ----- Original Message ----- From: "Douglas N Greve" <gr...@nmr.mgh.harvard.edu> To: "Kushal Kapse" <kka...@mail.med.upenn.edu> Cc: freesurfer@nmr.mgh.harvard.edu Sent: Friday, May 25, 2012 5:52:41 PM Subject: Re: [Freesurfer] fMRI time series in surface space it works for 4D, we do it all the time.
