Re: [Freesurfer] is this ok?

Thanks Bruce. I Am using version 3.0.3,..wat can i do to to get better pial surface images? IS it something to do with the skull stripping stage or is it the motion artifacts which cause a reduction in the overall resoution of the image?

Chacko.

Hi Chako,

I wouldn't worry too much about the inflated - it looks okay. Probably a result of the large motion artifact in your data. The pial surface is more worrisome - what version are you running? They are usually *much* better than this.

Hello freesurer users,

Is it ok to have such edges on the inflated surface?Is there something I can do to rectify this? THe second image is the brainmask and wm volume as seen using tkmedit.

(tkmedit subj1 brainmask.mgz lh.white -aux wm.mgz -aux-surface rh.white)

THanks in advance
