External Email - Use Caution
Dear Corinna,
The reason for this is that the volumes correspond to two different analyses.
The volumes from the two sources are highly correlated, though, so it shouldn’t
make almost any difference to use one or the other – but it you’re doing any
analysis with the nuclei, I would use the one from the thalamic tool, for
consistency.
Cheers,
/Eugenio

Subject: [Freesurfer] thalamus_proper or whole_thalamus volume measurement?
External Email - Use Caution
Dear all,
For the new thalamus nuclei segmentation there is a measurement for the whole
left and right thalami. The values are different from the thalamus_proper
values.
Which output should be reported as the volume for the whole thalamus?
Thank you
Corinna
