Dear SPM community,
I was wondering about how to interpret the intensity signal in the
segmented images of GM, WM and CSF. What's the range of the signal
intensity values in the GM image, for example? It depends on the range
of the raw image or does it have a specific interval?
And what does it mean to have a voxel with higher intensity signal
than another voxel, in the GM image? Does it mean that voxel has
higher gray matter volume if it is a non-linear only modulated
normalized GM image?
Thanks for any help
