Hi,
We are using DARTEL to perform VBM. After following the DARTEL manual, when
we are doing following Statistical Analysis:
1. a two-sample T-Test between control and diseased groups
2. gray matter volumes as covariate
3. Absolute Threshold equals 0.05
4. explicit masking using apriori/brainmask.nii
5. Contrast [-1 1]
6. threshold p = 0.01
7. voxel threshold = 50
Now, what can explain these out of brain 'activations'? What can be done to
avoid or reduce this effect?
Thanks
-Muhammad
