Hi Joao,
no, you need them. Otherwise you'll need to manually edit the wm.mgz volume to do things like fill ventricles, basal ganglia, etc....

I am using freesurfer for an inter-subject cortical thickness analysis. In order to speed things up, I was considering removing the sub-cortical segmentation step with -noaseg in the recon-all command line. I believe this will not affect my results, but I am not sure if some of the subsequent procedures are affected. Is it OK to do this then?
Thank you! Joao Pereira
