Dear Min Lui,
the glassbrain might deviate from your results depending on your sample. DARTEL is creating its own DARTEL MNI space depending on your normalized data. To relate your results to your anatomical images it is recommended to overlay the results onto an average image of your normalized T1-images. These normalized images are indicated in VBM8 by a prepending "wmr" (for Dartel normalisation) or by "wm" (no Dartel).
Regards,
Christian

After segmentation/smooth based on the dartel TPM and other default settings in VBM8 toolbox, the normalized, modulated, smoothed grey matter images were compared between groups with absolute threshold masking set to 0.2 and an implicit mask. Interestingly, the final brain appears to be not exactly registered to MNI space. Please see the appended image. Does anyone know why? Thank you very much for help and thanks Christian to bring such wonderful tool.
