Re: [Freesurfer] Basal Ganglia Segmentation

Hi Paul, yes, we know this happens - it's because of the way the manual training set was constructed, so that it has voxels labeled cortex there that shouldn't exist. The accumbens in general isn't all that accurate as it has no real intensity signatures at its boundaries, so we don't use it a

p.s. sorry, I should have looked at the images first. Everything I said still applies, but this looks worse than it should. If you put it one our filedrop I'll take a look On Wed, 24 Jan 2007, Paul Greenberg wrote: Hello, I'm having trouble getting an accurate subcortical segmentation (aseg.m

Thanks, Doug! I made that rectangle mark on the forehead actually. According to your suggestion, I tried tkmedit test orig.mgz -overlay test_mark.img -overlay-reg reg.dat The only mark that I could find is on the left side of the image in coronal view and nothing in sagittal view. So there is s

In step 3, was the registration correct? You can also try: tkmedit test orig.mgz -overlay test_mark.img -overlay-reg reg.dat the mark should be in the right place. [EMAIL PROTECTED] wrote: Hi all, I got some problems when I tried to overlay some maps one brain surface. The following ste

Cate, It will restart from the beginning. Making it behave like the 'make' utility, which checks input and output file dates and file existence before doing work, is a long-term goal for our recon-all, but not anytime soon. You can restart recon-all at particular stages by manually checking the
