Wed, 03/28/2012 - 23:11bgao老师你好，我想请教的问题如下： 1. 为什么在脑的研究里，alphasim校正比FDR，FWE更合适？ 2. alphasim校正时，选择不同的cluster size和p值结果会有明显的不同，我们如何知道选什么样的cluster size和p值才是合适的呢？选择p8194 reads

Wed, 03/28/2012 - 17:29Chen0075老师，您好！ 参照REST的视频讲解，我先分别做了两组被试者的组内分析（within-group analysis），然后做了“并集”计算得出一个MASK，用于2-sample t-test。得到了两组间有差异的脑区。 我的问题是：如果我继续做correlation analysis（与行为量表相关），应该是把分析的范围限定在“并集MASK”内，还是限定在存在差异的脑区？那种做法会比较好？ 另外，请问SPM可以直接做correlation analysis吗？16772 reads

Wed, 03/28/2012 - 15:22七色鱼老师您好， 我用去除白质和脑脊液的mask做alphasim校正，算出来的结果两次不一样，0.05以下的cluster一次89一次90，为什么呢？而且全脑的不是85吗，为什么去除白质脑脊液后还变大了。请老师指教。7705 reads
