[Freesurfer] cortical parcellation in anterior cingulate region

2007-06-25 Thread Marie Schaer
Hello everybody, Regarding the troubles raised in the mailing list and on the release notes about the anterior cingulate being misclassified with curvature.buckner40.filled.desikan_killiany, I would like to know if you have any updated version of the atlas available? In my subjects, most

[Freesurfer] long delay before tksurfer launches

Hello, Apologies for cross-posting (this list and martinos-tech), but I think that by posting here I might be able to reach a few more people who may have had the problem before and solved it. I have been experiencing very long load-up times, when running tksurfer. It can take up to 6 or 7

strace shows you the system calls being made by the program. When it's hanging for a long time, note the last few lines of output from strace and let us know what those are. The last one will be the call that is taking so long to finish. On Mon, Jun 25, 2007 at 11:56:00AM -0400, Robert Levy

Hi Bruce, Thank you for your quick response. Our problem, actually, is that when we visualize the aseg.mgz volume (with color-coded subcortical structures) we see that WM is classified as GM (left circle around insula in the figure) and GM is classified as WM (right lower circle in the figure).

[Freesurfer] Cortical surface tessellation and smoothing

2007-06-25 Thread Kai Li
Dear list, Is there a paper or any documentation describing how freesurfer tessellate and smooth cortical surfaces? In particular, does freesurfer use any specific variety of marching cube isosurface algorithm? Regular surface smoothing (like the Laplacian smoothing) may cause undesired

Hi Kai, it was described in the Dale, et al. 1999 paper in NeuroImage, or maybe part in that and part in the 2nd part of it (Fischl et al., 1999 also NeuroImage). They are both on our wiki (surfer.nmr.mgh.harvard.edu/fswiki). We don't use marching cubes, but a custom tesselation algorithm.
