Thank you Dr Bruce for the info! Is this command works on T1 images acquired from the spine or just the brain?

Hi James

after running recon-all you can use mri_cnr to measure CNR (which is
usually more interesting than SNR). Motion is harder. Martin investigated
this at some point, but I'm not sure where he left it
