Dear FreeSurfer Support team and Community I am wondering if someone can give me an explanation of the difference between g-w.pct and g:w ratio (as calculated by; fscalc lh.gm.mgh div lh.wm.mgh -o lh.ratio.mgh)
Will both these measures essentially measure the relationship between grey and white matter signal intensity but in a different way?
