Hi Jim, you can actually run mris_make_surfaces with -fix_mtl and it will inhibit all deformations in these regions. I didn't enable that by default as I was afraid it would mean missing a bit of entorhinal. In general it doesn't really matter as the gray and white volumes computed from the su

Hello FreeSurfer Folks- I've seen several threads in the archives discussing the expected inaccuracies in the pial, white, and orig surfaces running through subcortical structures. However, I've been unable to ascertain exactly how much and what kind of inaccuracy is acceptable. It makes sense

Hi Zheng, I'll leave 1) for Nick. As for 2, that's why we use the surfaces for cortical and white matter morphometry- they are more accurate than the voxel-based techniques. cheers Bruce On Tue, 27 Nov 2007 [EMAIL PROTECTED] wrote: Hi, I have two questions: 1) I just upgrade our intel M

Zheng Hui, 1) We don't yet have a system with the new Leopard OS, but have it on order, so we should be able to test this soon. Does the file /usr/X11R6/lib/libexpat.0.dylib exist on your system? 2) There is not a way that I know of to regenerate the aseg.mgz file using the surfaces. There ar
