Re: [Freesurfer] WM Hypointensities

Hi Andrew,

I see you specified '-nonempty'. 'wm-hypointensity' is probably excluded because the voxel count is zero. I'm only looking at this from programmer point of view. I don't know how wm-hypointensity is assigned in recon-all-clinical.

Best,

Hi Andrew,

I can't answer if wm-hypointensity is supported in recon-all-clinical. I'm assuming that you obtained aseg.stats by running mri_segstats. How does your command look like?

Best,

Hi Freesurfer experts!

I am hoping to extract the wm-hypointensity data from some recon-all-clinical runs. I was able to extract aseg.stats information correctly but noticed there was no information regarding the wm-hypointensities.

Is this supported by recon-all-clinical?

Best,

Andrew
