I think it is probably ok, but why not use the ICV from v7?

External Email - Use Caution

Hello Freesurfer Developers,

I have extracted ICV measures using samseg from freesurfer v7.1.0. I would like to use this measure to correct the cortical volumes that i have extracted from the same subjects using freesurfer v6.0.

1) Is it advisable to use ICV measures from another freesurfer version to correct the cortical volumes that i have extracted from the same subjects using freesurfer v6.0?

OR

2) Do you advice that i should re-calculate the cortical volumes using freesurfer 7.1.0 in order to correct them using the ICV measures extracted from samseg?

Nice weekend!

Jay
