Hi Maurizio
the orig.mgz has been converted to 1 byte/pixel and 256^3 1mm isotropic.
You can use mri_convert to go back to your original data space via:
mri_convert -rl orig/001.mgz <input volume> <output volume>
cheers

External Email - Use Caution
Hello,I am trying to run a VBM analysis by using the white matter and the grey
matter masks from
Freesurfer, because, often, other tools are not able to calculate a correct
white matter and grey matter
masks.
When I have these masks, I have to apply them to my original T1 images.
However, the original T1 is in
different space. I can resample the ROIs (WM and GM) in order to apply them to
my original T1, but my
question is:
Can I use the orig.mgz from Freesurfer as my T1 for VBM, or does it have
different intensity from my real
T1 acquisition?
Thanks,
Maurizio
