Hi Gang and Taylor,
Thank you so much for your reply and suggestions.
I have rerun the code with a small change. Instead of this
-bsVars
'Group*Sex+Group*Age' \
I have used this option under the 3dMVM command
-bsVars '
Group*Sex+Age' \ ---- this is now giving me the same result for F-test and t-test. In terms of syntax, what is the difference between these 2 options in the 3dMVM command?
Only issue with the outcome is that- the x,y,z positions of the clusters are different in the cluster report for the tests, though visually the image shows exactly the same clusters. I am attaching side-by-side photos for F-test and t-test. Also the 3dClust outcome is attached (both are bi-sided, F value for Pthreshold= -4.13 to 4.13 and t score for Pthreshold= -2.0322 to 2.0322. That satisfies F=t^2).
