Hello SPM VBM experts
I tried to compare the differences between two mouse groups ( control vs knockout), I was able to do registration, normalization and segmentation nicely. I did 0.5 mm isotropic smoothing Then I did 2 sample t test on grey matter with p=0.01 with 200 clusters, I got the above results. I am wondering that why I am getting few clusters with significant voxels? Does this look normal? Please share your suggestions.
