Hi Francesca,
I would load the surfaces over the T1 volume and take snapshots of that. You can also do tools->configure->surface and make the lines thicker, as they are hard to see if they are only 1 pixel wide.
cheers, Bruce

Goodmorning:
My problem is related to the fact that I would like to save an image in whatever format suitable for a presentation (from my free-surfer subject). I am not sure which is the volume I should download to begin with and what I should load on it - afterwards - to show the cortical GM segmentation in the three planes.
Thanks,

can you describe the problem in more detail?

Hi:
I am having troubles in preparing a picture showing MR image segmentation
in
the coronal, axial and sagittal planes.
Any light on that?
Thanks, --francesca

Hi Wan,
they haven't been normalized. Typically you would normalize by the total intracranial volume, which can be a bit tricky to get from only a T1. If you normalize by total brain volume, that should be a bit more conservative, as it would normalize out total atrophy.

Hi, I have a question. I am getting the gray volume for a standard area (G_subcallosal) in different brains (male and female) with different conditions.
If I want to compare these volumes, should I normalize them with the
total
brain (or hemisphere) volume or can I use these results directly? I understand that the FS fills the volume from a particular brain into a standard brain. So, are the volumes already normalized? Thanks,
Wan
