wow, I've never even looked at the ?h.curv files before. Looks like there is a lot of info but only on a global (whole hemi basis). Some of the measures are different (eg, min and max curv rather then mean or gaussian). I don't know whether these would be helpful in your app.

External Email - Use Caution

Hello Freesurfer developers,

I am attempting to build a brain age estimator with FreeSurfer output. However, I am having some problems disentangling Freesurfer stats output. I will be using only the Desikan-Killiany atlas cortical segmentation. I have identified these files as useful:

aseg.stats   -> subcortical segmentation features lhaparc.stats -> DK cortical segmentation left hemisphere features rhaparc.stats -> DK cortical segmentation right hemisphere features lh.w-g.pct.stats -> DK cortical segmentation left hemisphere grey matter - white matter contrast features rh.w-g.pct.stats -> DK cortical segmentation right hemisphere grey matter - white matter contrast features wmparc.stats -> white matter close to DK cortical segmentation areas features

However, I checked these two files too:

lh.curv.stats rh.curv.stats

But I don't have a clear idea of the meaning of the features in those files. For what I understand the features are the mean and standard deviation of the white matter surface and the pial surface. However, these measurements would be redundant if I include the features from xhaparc.stats, wouldn't they?

Thanks for your help!
