Dear All
Please could someone clear up my confusion!!!!
I am doing some VBM pre-processing using the unified segmentation method (as per the
VBM toolbox) using SPM5...
I understand that the segmentation procedure includes bias correction and non-linear
registration but can not seem to ascertain if there is any normalisation of tissue priors or
original images before the iterative algorithm kicks in.
The A+F 2000 methods performed spatial normalisation first and this seems to be alluded
to in some literature but am I under the wrong impression that now in SPM5 all 3
processes occur together....
1) segmentation, bias correction, normalisation
2) modulation
3) smoothing
Thanks
Sarah
