External Email - Use Caution
Just to clarify, by that I mean would the NIFTI converted from orig.mgz (with mri_convert) be different than the NIFTI produced by dcm2niix from the raw DICOMs?
Thanks, Colleen

Thanks Bruce. Will the orig.mgz file be different from the raw data in any significant way?
Thanks again, Colleen

Dear Freesurfer developers,
A collaborator shared with me Freesurfer outputs, but I would like to some analyses requiring the scans in NIFTI format. I understand mri_convert should do the trick for this, though I was wondering whether I should use "orig.mgz" or "T1.mgz" to convert back to the original T1 NIFTI files.
Many thanks, Colleen
The orig.mgz is closer to the raw data than T1.mgz, but it will be different in a number of ways. First, it will be 256^3, 1mm voxel size regardless of the dimensions of the raw data. Second, it will be 8 bits (0-255) with some rescaling.
