    Dear all, I am using a brain surface coil to do some resting state fMRI experiments. As a result, the signal I'm getting isn't homogeneous - the images being brighter/having more signal at the surface of the brain than basally. I am new to the resting...

        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。

    Dear Experts, I would like to perform functional connectivity analysis within DMN of resting state datas from 2 groups. After preprocessing and band-pass filtering. I'm going to perform ICA and select the components having higest correlation within DMN (...

    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,...

    What's the content of constant and quadratic removed?Is the constant same as the Global signal?  Look forward to your reply!
