Hello All,
I am a newbie when it comes it analysing MRI data, so please excuse me if
this is a silly question. I read somewhere that bias regularisation is not
really necessary with modern MRI scanners, as bias nonuniformities are
relatively small. Is this so? How often is it the case that the default bias
regularisation setting in SPM5 of 0.0001 needs to be adjusted? How would I
go about determining whether I need to adjust this setting (as part of
conducting a VBM analysis)?
Thanks in advance for any help you can provide me with.
Regards,
