multivaraite and bivariate GCA

大家好!

我用REST跑了同一个ROI的voxel-wise multivariate GCA和bivariate GCA,结果是一模一样的。我的理解是multivariate会控制其他voxel对当前两个voxel的granger causal connectivity的影响,bivariate GCA则没有。为什么结果是一样的呢?是不是multivariate只对ROI-wise起作用?

谢谢大家!祝大家元宵节快乐~

DPABI中的IMAGE RESILCE 对灰质密度文件(WRP1)重采样后没有可用的密度数值

老师们好,我用DPABI中的IMAGE RESILCE 对灰质密度文件(WRP1)重采样后,无论目标的voxel size是多少,所得图片文件的各体素均没有可用的密度数值,只分为0或1,请问怎么解决?而对mwrp1文件进行处理是正常的。换了别人的电脑也一样。

DPABI/DPARSF视频教程V2.2与DPABI/DPARSF特训营

近日,静息态功能磁共振数据处理教程V2.2正式上线。V2.2版课程主体为2017年12月13日-19日的第二届人脑连接组神经影像研讨班暨脑成像数据分析与论文撰写特训营的授课视频,加以剪辑修订,免费开放供相关研究人员学习。该版课程在内容全面性上为历次之最,不仅结合最新研究结果介绍了静息态功能磁共振的基本概念、常用计算方法、DPABI/DPARSFA使用等基础知识,而且根据特训营学员需要补充DPABI动物数据处理专题,更添加了备受关注的可重复性与多重比较矫正专题、R-fMRI动态性专题。 V2.2全部课程共10个专题已上传至http://rfmri.org/Course#Chinese,欢迎大家观看!

另外,由于大量用户反映在线教程学习缺乏互动,并且对于DPABI/DPARSF运行中的诸多报错不能得到有效解决,兹定于2018年3月24日至26日在中国科学院心理研究所举办为期三天的DPABI/DPARSF特训营(为DPABI/DPARSF国内独家授权培训)。
