Dear Jason,
Thank you very much for the interest in our tools.
We understand that intracranial volume (ICV) is a crucial covariate in
volumetric analysis and are working on incorporating it into SynthSeg (and
SynthSeg+). The good news is that we have a prototype pretty much ready and it
should

Hello!
I am using SynthSeg (SynthSeg+), and so far testing this on my own data is
going well.
A question I have for the forum is whether it is possible to get additional
measures, such as whole brain volume and total intracranial volume. Both of

Hi all,
I am looking for an accurate method of calculating whole brain volume (WBV)
from a spreadsheet of FS MRI data. I had previously been using the following
method:
1. Sum the following: CSF, lateral ventricles, 3,4,5 ventricles, and the
choroid plexus
2. In a second column, sum the follow

I knew this question has been asked before and it was suggested to use
SupraTentorial as the whole brain volume. I am working with ADNI data and
cannot find this measurement from UCSFFSL table. As my understanding, UCSFFSL
table was generated by Freesurfer 4.4. I was wondering which structures
Hello All,
We are looking into alternative measures for whole brain volume to use for
covarying, and the previous topic mentioned mris_volume as a possibility
but it isn't located on the top of the aseg file. Has it been moved?

I have a follow-up question to my inquiry about whole brain volume. I have
some subjects completed with the older version, where I have BrainSegNotVent,
and some subjects completed with the new version. If I combine Supratentorial
with cerebellum to calculate whole brain, is this comparable to
I think I just found the answer to my question on the wiki:
More specifically, the CorticalWhiteMatter measurement is calculated by
determining which voxels are within the WM surface.
So the term "cortical" does not mean that deep structures are left out, it is
referring to how the measur

You're correct that it doesn't include cerebellum. I think it includes
corpus callosum and internal capsule but I defer to Doug who would know
for sure.

Thanks, Allison. This actually leads me to another question though. It says
in the wiki that SupraTentorial
includes Cortex + CorticalWhiteMatter + SubCortGray. I notice that subcortical
white matter is not mentioned. Does this mean the corpus callosum and internal
capusle is left out? Als
It might be SupraTentorial depending on what you are looking for. They are
all explained on this wiki:

file called BrainSegVolNotVent. The newest version no longer has this. I am
wondering where I can now find a measure of whole brain volume?
Thanks,
