a) yes b) yes, of course. We are always trying to improve things, so the new versions are almost always a little different

Dear FreeSurfer Users,
I have run recon-all on data using both FreeSurfer versions 5.3.0 and 6.0. FS v6.0 generated files named lh.aparc.pial.stats and lh.aparc.stats, whereas FS v5.3.0 created only lh.aparc.stats. I wanted to verify two things:
(a) Is it right that surface areas in lh.aparc.pial.stats correspond to pial surface (boundary between gray matter and CSF) of ROIs in the DK atlas, whereas lh.aparc.stats contains surface area at the boundary between gray matter and white matter at those ROIs?
(b) There were differences between the values in the lh.aparc.stats from FS 5.3 and FS 6.0, despite my using the same data and same seed (i.e. -norandomness flag) for "recon -all" under both versions. Is it right that there are differences between the algorithms in FS 5.3 and FS 6.0 that could lead to this?
Thank you.
Best,
Chintan
