[Freesurfer] general questions

Hi all,

I'm new to FreeSurfer and so have a few questions that you may be able to anwser.

My first question is ; when I am making white matter edits do I need to edit every single slice where the inaccuracy is or would every second or third slice suffice to prompt FreeSurfer to autocorrect?

Secondly, in many of our FreeSurfer images, the horn of the lateral ventricles in the coronal images are being excluded from the white matter - is there a way to stop this from happening?

Finally, I find that Freeview is a good way to view the images and although I know it is possible to make some edits such as filling in voxels etc., I wanted to know if it was possible to add control points like that in tkmedit?

Thanks, Deirdre
