almost, it will also change the center of ras coords (stored in the volume), which may not matter to you, but changes how you get from voxel indices to mm coords in the scanner. This is all documented (thanks to Doug!) on our wiki.

Thanks, Bruce.
- No, it's all done in what we call "conformed" space, which is the
original volume interpolated to 256^3, 1mm iso and 8 bits/voxel
If the original volume is 256^3, 1mm iso and 8 bits/voxel, whether all output results are same as the original space?

I have another questions:
1> If the input binary segmentation is topologically correct, whether the surface generated with the utility mri_tessellate is topologically correct.
2> All output results with "recon-all -s bert -autorecon-all" are based on normalized space (template), is it right?

Hi Yan,
- We generate a file named ribbon.mgz, which is the filled interior
etween the ?h.white and ?h.pial surfaces. 2. This is a whole research topic, and most of the stuff that happens after the segmentation is for doing this. The utility mri_tessellate will generate a surface from a binary segmentation but it won't be smooth or topologically correct. cheers, Bruce On Mon, 29 Jan 2007, yanxia wrote:
Dear All, I am a new user of FreeSurfer. I have two questions: 1> How can I use mri_surf2vol or others to convert .pial to .mgz? 2> I have a binary .mgz file. How can I generate .pial file so that I can view it with tksurfer? Thanks. Yan
