Re: [Freesurfer] Standard deviation map

the thickness varies with geometry (e.g. sulci are thinner than gyri). cheers, Bruce On Thu, 20 Sep 2007, Inês Souta wrote: Well, I'm dealing with a patient with an heterogeneous lesion. Somehow, the lesion area seems to have misled the algorithm in terms of white and pial surface definition

Re: [Freesurfer] Convert values in label

Yes, it will! thanks a lot Inês 2007/9/8, Bruce Fischl [EMAIL PROTECTED]: I think if you load the label and load the thickness as an overlay, then save the label it will put the thickness values into the last column of the label file. cheers, Bruce On Fri, 7 Sep 2007, Inês Souta wrote

[Freesurfer] Switch hemispheres

Hi, After processing the hole image I realized that the orientation of the original .mgz file was wrong and I've ended up with switched hemispheres. The right hemisphere is where the left should be, and vice-versa. Otherwise the orientation is right. Since I've already made manual edits, is the

[Freesurfer] Excluded gray matter - pial surface

Hi there, I need to edit the pial surface. It isn't getting out far enough all over the cortex. I'm sure it is not a skull stripping problem. Do I need to add control points everywhere in order to correct this? Isn't there another way? Thanks Ines ___
