HI, wondering if there are thoughts on this question I posted a week ago? Repeated here: I'm comparing output of Freesurfer5.2 to 6 on the same set of brains. The "5th ventricle" (Cavum septum pellucidum) is not being detected by 6. I had eyeballed the output from 5.2 and convinced myself it was reasonably well detecting this developmentally abnormal finding pretty well. I am wondering what changed in version 6, if anything, that could explain this?

Hi Sarah
can you upload your subject processed with both version? There isn't anything explicit we have done that would change the 5th ventricle segmentation as far as I know.
5.2 was an orphan version, so hopefully we can sort this out and you can stop using it cheers Bruce
