Dear all,
In the statistical analysis, we need to choose a binary mask.
What kind of binary masks I can apply? If I turn to the group-wise GM mask, it seems there're too many comparisons, leading to failure in the tfce+fwe correction (p<0.05).
Can I use the |Z|>2 of the Z map as the binary mask instead to reduce the number of comparisons?
Thanks!
