Real data analysis results. # of cluster which has over 20 contiguous voxels with p–value less than a specific threshold for testing the genetic and environmental effect by using EM method without smoothing, smoothing with Gaussian kernels (FWHM=3mm, 6mm and 9mm) and TwinMARM method at the 1^st and 10^th iteration.
