Hi everyone,
I'm using a frozen version of FS v4.0 and I have a subject with rather large ventricles that don't get filled properly (surfaces and aseg are off) during recon. I can't really find a good fix in previous messages besides to upgrade FS, since it seems like the newer versions will handle it better. Are there any procedures I can follow with 4.0 to fix things (filling in the vents on wm.mgz, etc.)? Thanks!
Andrew
Hi Andrew,
you can fill them in the aseg.mgz with tkmedit if you want. The newer versions do better with large ventricles, but if they are big enough we may still mislabel some of it.
cheers Bruce
