AlphaSim

AlphaSim parameters

AlphaSim is a Monte Carlo simulation. 

Schematic representation

1. FWHM: 4
2. rmm: 5;
rmm is used to define connection cretiria. For example, when voxel size = 3*3*3, rmm = 4: face connection; rmm = 5: edge connection (SPM use this); rmm = 6 corner connection (FSL use this).
3. threshold: 0.01
4. iterations: 1000
5. mask:image
