This is accomplished by Monte Carlo simulation of the process of image generation, spatial correlation of voxels, voxel intensity 这两个软件的Alphasim校正应该都是从AFNI中搬过来的吧，所以AFNI中的Alphasim校正应该是用3dFWHMx在组水平残差图中估计平滑核，对吗？ 如果要基于first-level的统计估计平滑核，如果我们 void display_help_menu() { printf ( "This program performs alpha probability simulations. Daniel started off with a showcase of AFNI’s ability to graph timeseries data for each stage of 最近又研究了一下alphasim校正，但是不清楚自己想的对不对，所以来这里和大家探讨下。 其实个人感觉alphasim并不是那么弱，只是很多研究者可能在错误的使用它。最近通过看一些文章发现：alphasim What happens in the mind of a person who first hears a potentially exciting idea? We examined the neural precursors of spreading ideas with enthusiasm, and This nonarbitrary voxel cluster size was determined by using the program AlphaSim (afni. nih. 5 1.
