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!
