Hi Linn,

I have never done that, so I am not sure, but since it is likely affecting the surface, I think you need to do it in the base, to get good initial surfaces. You may have to do it again in the long stage. Start with the base.

Best, Martin

To: Bruce Fischl <fischl@nmr.mgh.harvard.edu mailto:fischl@nmr.mgh.harvard.edu>

Hi everyone,

I am registering hyperintense lesions as "lh-lesion" or "rh-lesion" and I was wondering if it is better to do this as the base or the long stage. I see that the freesurfer wiki page says I can do it at both stages depending on the problem, but I was not sure if lesion registration counted as "incorrect labeling" or "correcting the volume of importaint structures".

Thank you in advance!

Regards Linn Norbom
