Hello,
I have a series of datasets with skull stripping issues - namely left over
dura/vasculature in the occipital cortex, and some in frontal areas.(Attached
is a jpeg of the type of issue. It's pervasive throughout the slices, across a

Hello -
I have two questions:
1) I noticed on wm.mgz volumes that were segmented properly, that even when the
ventricles were
automatically filled in, on some slices they are somewhat patchy (partially
filled in with white, with some black/blank voxels).

I am trying to compare normalized segmentation stats across groups. We are
adding control points to the white matter in an attempt to push out the pial

Hello -
I am comparing aparc stats across several groups of data, and just noticed that
recently processed groups do not have corpus callosum values... which made me
wonder if different versions of freesurfer will produce different aparc data...
Can aparc stats from an older version of
Hello - can anyone tell me where I can find details on what aseg stats include
and exclude from each measurement? The ones I need in particular are:
Left-Cerebral-White-Matter Left-Cerebral-Cortex and IntraCranialVol. I'd
like to understand if L-Cereb-Cortex means just gray matter,
