Hi Sue
you could take the eTIV from 5.0 and the aparc stats from 5.1.0. I
believe we already distribute the updated template but it's not used. Nick:
do you want to send around a patch to recon-all that people can use before
5.2 comes out?
thanks

Hi all,
Using previous versions of FreeSurfer, we have used the eTIV as a covariate for
our volumetric analyses. We
have been using the eTIV numbers from 5.1.0 for new studies. What would you
recommend using for subjects who
have been run with 5.1.0? Can you make the template available publicly, or
would it be legitimate to take the
eTIV from 5.0 and the aparc stats from 5.1.0?
Thanks,
~Sue

can you send us an example? In the ones we've looked at the older
versions were more stable.
Alternatively, we can send you a new template that Avi Snyder generated
that you could try out

Well, I am using version 5.1.0. I have had same issue in fewer
subjects when I used
the older version as well. Any comments about that?

recon-all
Hi Ayaz
what version are you running? There appears to be an instability in
the
eTIV calculation in just version 5.1 (not before or in the upcoming
5.2)
cheers

Dear All,
After running recon-all, I noticed several subjects that sum
of WM and GM
is
bigger than ICV. I have re-run these subjects and the
results is the
same
sum of GM and WM is coming out to be bigger than ICV.
Any suggestions? I need to calculate normalized volumes.
