Hi Heather, the ICV is mostly unrelated to the other volumetric
measures. what do you mean that you are having problems getting ICV to
fit correctly in your sample?

We are having a difficult time getting the ICV to fit correctly in our
sample, but the segmentions and parcellations look accurate. I
believe that the ICV is generated from the talairach.xfm early on in
the processing stream, but then further processing for
segmentations/parcellations is done.
So, does the ICV measure affect regional brain volumes in any way, or
can we trust the volumetric measures to be accurate even if the ICV is
not?
Thank you,
Heather Lugar
