Dear FreeSurfers!

I want to do bias correction on some T1 and T2 images. I have heard that you can do this by using mri_nu_correct.mni

how should I use this command?

I could not understand this (I am a beginner in FS) : https://surfer.nmr.mgh.harvard.edu/fswiki/mri_nu_correct.mni

would it be something like : mri_nu_correct.mni -i <path-to-input-file> -o <path-to-where-output-file-should-be written + filename>?

Thank you very much!

Kind regards, Cris
