Dear FSL, I have used FEAT for preprocessing, What should I do to obtain a better structural-to-standard registration,I have used non linear registration for preprocessing Thanks VasudevC On Tue, Feb 18, 2020 at 6:47 PM paul mccarthy <[log in to unmask]> wrote: > Hi Vasudev, > > I'm afraid I have to disagree - the structural-to-standard registration is > quite poor.
