There is no one simple button for VBM analysis, rather you have to go
through several stages by yourself.
For the most current version of SPM5, first, you can use the
segmentation button to segment the images. You don't really need to
generate any output images at this stage, but it is recommended to at
least generate the native space Grey Matter map to see if something goes
After applying the segmentation, you should get some sn_*.mat parameter
files, go to TASKS->Tools->DARTEL tool->Initial Import, and import those
parameter files to generate rc1*.nii,rc2*.nii
Then select Run Dartel (create template) to generate the deformation
After that, you can then select "create warped", remmeber to choose
"Modulation" in the option.
Smooth those modulated, normalized images, and use the Basic models to
analys your VBM.
