bivariate or multivariate coefficients
请问老师rest作基于roi之间的gca,想看两两roi之间的效应连接,bivariate和multivariate coefficients之间的区别,谢谢老师!

Hi REST experts,
请问,用rest1.8计算degree centrality的时候那个dafault mask 是全脑mask还是只有灰质啊?
Why do I see this error message when clcking on the "Slice Viewer" on the REST opening page
image_toolbox not valid
> In rest_sliceviewer>InitControls at 1053
In rest_sliceviewer at 74
In rest_sliceviewer at 38

Hi, Yan, how can I do the statistical analysis after I have obtained "szDegreeCentrality_PositiveBinarizedSumBrainMap". Within-group, do the FDR correction? Thanks!
各位老师您好:
我附了三张图片:这三张都是六个脑区的ALFF,依次向下的顺序是 mALFF、mfALFF、zfALFF ;四种曲线颜色代表不同条件,例如静息前后等等;
(1)我用mALFF、mfALFF、zfALFF画出的折线图差别较大,我不太清楚为何原因,按理说,四种条件下,也就是纵向看的话,趋势应该是相同的,为何趋势不同;
(2)脑区与脑区之间对应的纵坐标的值可以相互直接比较吗?
Hi all,
I have an artifact in my data that is very sharp in frequency, I think a notch filter would be ideal to remove it. Is there any notch filter implemented in rest? if not, Could anyone suggest an alternative approach?
thanks

老师们好,
我已经运用ICA方法提取出病人组及正常组的DMN网络,现在我想比较之间的差别。取了10个aal脑区的ROI,用DPARSF做ROI-wised analysis, 计算出了10个ROI之间两两相关的FC,下一步想比较两组间10个ROI的FC强度之间差别。我想请问接下来如果要进行two sample t-test的话,应该如何进行?
各位老师您好:
我突然想到ALFF是直接滤波之后提取的,没有经过regress这一步,或许我不知道这原理是什么,我想知道为什么不regress之后作ALFF?
谢谢
