Submitted by wangkangcheng on Fri, 11/30/2012 - 17:31 老师好,我在使用了DPARSFA2.2时,选择了degree centrality这个选项,在给出的一些文件中,选择了zDegreeCentrality_PositiveWeightedSumBrainMap这一类文件做了吸烟者和控制组的双样本t检验。听了老师的在网上的讲座,有些问题希望确定一下。 1、R值的阈限是从0.25开始取,一直取到1之后,做的这些结果的平均吗? 2、加权值不仅是考虑到了每个voxel和全脑其他voxel相关显著数目,而且考虑了值的大小是吗? 3、转化成z值的数据(以z值开头的文件)和平均值的数据(以m开头的文件),选择哪个较好?

(2)有什么方法可以剔除这些体素么? 谢谢大家!
