Hi freesurfers,

Following recon-all I have a collection of folders inside the subject folder.

Inside the folder "mri" I have collection of files:

1. What is the differnce between the file "orig.mgz" and the file "norm.mgz" ?

2. Why the voxel dimentions are differnt? (i.e In norm.mgz the voxel dimentions are equal while in orig.mgz it is not)?

3. Is it correct if I convert norm.mgz to "nii" file and use it as a "T1" for further processing?

bests,

John Anderson
