External Email - Use Caution        

Dear Freesurfer,

Does my T1 MPRAGE need to be in a particular orientation prior to running recon-all? Meaning should I use mri_convert to change to RAS orientation to avoid any L/R confusion with the output measures.

For instance, mri_info says the orientation: 
MPRAGE = LPS
orig.mgz = LIA
T1.mgz = LIA

I'm confused because if you bring up an image in freeview, say the T1.mgz, it uses the RAS coordinate system.

Thanks,
Abid
