External Email - Use Caution        

Hello FreeSurfer Experts,

I converted the aseg.mgz file to aseg.nii using mri_convert command,
the aseg.mgz  file is located in the directory below based on your tutorial:
tutorial_data_20190918_1558/practice_with_data/Subj001/mri

When I open the file aseg.nii in a different application,
the original orientation is not sagittal.
In the MRI protocol, the original orientation is sagittal.

Could you please help to tell how to set the original orientation 
of output images to be sagittal? 

Thank you in advance!

Best regards
Haiyun
