[MINC-users] nu_correct & masking

[Richard Boyes]

Hello everybody

Regarding use of a mask with nu_correct, I have available
to me two types:

1. A brain mask that excludes CSF completely - ie WM, GM
    only

2. A 'filled' brain mask - ie includes the CSF in the sulcal
    and ventricular spaces.

My question is, which mask is more effective? Intuitively
I thought that the CSF mask would be better, as it gives 3
classes in the histogram, which gives N3 3 histogram peaks
to optimize over.

Thanks in advance
Richard
