Meta-Analysis Tutorial #2: Seed-Based d Mapping

Overview of Seed-Based d Mapping

Instead of using the maps generated by GingerALE, which determined significant overlap based on p-values, we could use permutation testing, a technique that is more robust to outliers and any violations of the assumption of normality, and which uses the data itself to construct a null distribution. For those who prefer this method, we will learn how to use a package called Seed-Based d Mapping (SDM), a free, open-source software package that can be used with SPM.

In addition to using permutation tests, SDM
