Hi Jay, Permutation testing will give the most accurate results.

Hi Experts,

Which option is best to use: mc-z or perm? I have read that perm gives more accurate results than mc-z, as it uses the actual data rather than fake data to estimate the null distribution. When I use perm, I get no significant clusters. When I use mc-z, almost all clusters are significant.
