Dear SPMers.
I'd like to get some advices about the volume calculation with raw or modulated GM/WM/CSF.
I got the volumes of GM/WM/CSF with Gaser's script(with raw image),
and also calculated the volumes with modulated images after optimized vbm protocol.
The two volumes (with raw and modulated images) showed discrepancy.
Dr. Gaser advised to me the volumes with raw image is more frequently used for papers.
But, I'd like to use modulated image for the subvolumes with masks.
Is it acceptable the use of modulated image for the volume calculations of GM/WM/CSF volume
for research or publication?
I will appreciate any comment.
