Hi there,
I'd like to simulate VBM data and was wondering about the structure of
modulated voxels over space. Does anyone had a look at this?
Say I want to create a 4D matrix (x,y,z,subjects), how data are expected
to be distributed before smoothing? (correlated and kind of normally
distributed in the 3D space, or normally distributed but uncorrelated or
normally distributed in the subject dimension only ?? there are many
possibilities).
Thanks a lot in advance for any advice
Cyril
