An overview of cluster correction in fMRI and a demonstration of how it works. This is an appendix to the fMRI Short Course: [ Ссылка ]
For a demonstration of how to run cluster-correction simulations with AFNI's 3dClustSim, see this video: [ Ссылка ]
Why use a cluster-defining threshold of p=0.001? See the original Eklund et al. 2016 paper ([ Ссылка ]) and also a video overview of the issue: [ Ссылка ]
