Hi,
I found this by accident, but we ran a phantom through the unified
segmentation in SPM5. I've attached a screen shot of the input (which was a
spherical phantom) "vbm_problem_remprage.jpg" and the output GM map
"vbm_problem_wc1.jpg"...which looks very much like a brain (and spatially
correlated with the prior at a value of about 0.94). This makes me worry a
bit about the influence of the priors on the unified segmentation. Has
anyone seen this before?
