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
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....
