    尊敬的老师:      您好!我正在学习统计分析这一部分内容,作为一个初学者,对于非参数检验和多重比较的适用场景有些不确定。      具体来说:置换检验后能否进行FDR或者高斯随机场校正?

    尊敬的严老师:       您好!学生刚开始接触静息态数据处理,所以按照您教授的步骤进行操作时总是有问题, 我就在想可能是因为我的数据整理有问题,所以我希望你帮我看一下下面这段MATLAB显示的问题, 同时可以麻烦老师教授一下如何在数据处理前整理数据吗?预处理之前的数据整理有何要求? 谢谢老师,盼回复!   Read E:\data\Subject_001\0000001.dcm etc. 引用了不存在的字段 'ProtocolName'。   出错...

    Dear experts, I tried to run the seed-based functional connectivity analysis with the latest version of DPARSFA and Matlab 2015. It all went well for a while, and then I got the following error (attached are two pictures/screenshots of the error). It seems...

    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。
