        您好,老师!     我最近准备做统计分析时有一点小疑问,之前DPARSF的界面上有一个选项是nuisance covariates regrssion,这个是已经把协变量做了一个回归分析,那之后统计板块的two-sample T-Test里还要再加协变量的有关文件吗?关于协变量这块不是很懂,希望老师不吝赐教。

    各位老师,我想对FC获得的相关性系数做病例组和对照组的t检验,经过z变换以后的值做双样本t检验得出的结构就是最终结果吗,还需不需要做类似于多重比较校正的检验?谢谢。

    各位老师好! 我想请教一个问题:在进行reho值的组间比较时,我想把被试的结构像作为协变量加入统计,选取的是每名被试的灰质密度(通过VBM分析得到的,进行了normalize的结果)。但是因为功能像和结构像的dimension不同(功能像是61*73*61,结构像是121*145*121),REST会因此而提示无法运算。请问这一问题该如何解决? 我试了一下REST里的reslice image功能,发现如果把结构图像的voxel size改为3*3*3,得到的结果就将dimension变为61*73*61了,...

    老师您好,怎么理解功能像与结构像是线性相关的平动与转动,而不是扭曲的?
