HI Guido

skipping the aseg will mean you need to do a lot more manual intervention to get good surfaces (e.g. filling ventricles, "spackling" wm inferior to hippocampus, etc...), so I wouldn't recommend it

Hi FS Experts

I'm using FreeSurfer to process my T1 data in order to get white and pial surfaces from it.

I have a questions about usages of this file 'aseg.mgz'. In the 'recon-all' pipeline, there are some steps in which I can use it or don't use it depend on  if I want or don't. I wonder What are the differences in the result in each option?

My goal is skip the '-careg' step to save time because I'm not interested in volumetry.

I'll be grateful if you can help Being all for now, I await a reply
