    各位前辈好!       我现在做了一个两样本t检验,打算在rest里面使用alphasim来估计cluster size,首先需要估计平滑核,具体界面见附件。里面需要输入三个文件才能估计平滑核,其中中间的mask file是做两样本t检验的mask吗?那其余的input statistical map和 FWHM of statistical map需要输入什么呢?       谢谢各位!

        rest 里面的extract ROI Signal功能,我用自己弄的90个脑区作为ROI,最后得到的resultCorr.txt(90*90矩阵),是90个脑区的相关系数,接着去除了这90个脑区的协变量,再做了功能连接之后的ROI-WISE也得到FCMap.txt 或zFCMap.txt(90*90矩阵),这个也是90个脑区相关系数。那么问题来了,zFCMap.txt和resultCorr.txt这两个的关系是什么呢?是去除了协变量吗???

    (新手)我有三组数据要进行分析,下面是我尝试的分析处理过程,但是不知道对不对,求老师指导一下,谢谢! 利用rest首先进行的ANOVA,找到差异性显著的clusters,(不知如何选择ROI做mask,所以只是单纯的存为clusterA.txt)。然后进行two sample t-test,又出来一些差异性显著的clusters,3组每进行两两比较就得到3个这样的clusters,分别记为cluster1,2,3。然后我将clusterA中具体的cluster与cluster1,2,3中的进行比对,...

    各位好:          我研究的是中风病人和正常人ICA网络的组间差异问题,拿运动网络为例,我们发现病人组和正常人组的单样本图差异很大(前提是卡了同一个阈值),主要是涉及的脑区范围存在显著差异,正常人组单样本图比较正常,病人组的单样本图明显比正常人组小了好几圈,为了定量表征两组间这种差异,体素个数上的差异(或者说网络覆盖程度的差异),我具体的应该怎样统计呢?我的预想是将每个被试的运动网络的map的体素个数输出来,然后对正常人和病人进行双样本T检验,但是,问题是...
