静息态数据ANOVA比较之后如何再进行两两比较?

请教一下三组被试,患病组,共病组和对照组,ANOVA比较后,想进一步知道两两的差异还可以用t检验吗?会不会造成了多重比较?REST能解决这个问题吗?

mask出错了,能怎么改正么

各位老师们好!

最近处理的一批数据,其中有些被试是头部上下颠倒的,于是用fsl翻转过来并在fslview里看着正常后,后用DEPARSFA处理。结果是,那些头部曾经颠倒了的被试result都为空,而其他没有颠倒的被试都挺正常的,看PicturesForChkNormalization也是那些颠倒的被试normalize没配齐。

Folder structure / directory tree for repeated measures

 Dear all,

有关使用rest计算degree centrality结果输出的问题

严老师您好,我做了30个正常儿童中心度,在rest计算DC的界面有两个输出结果分别是output directory for weighted sum和output directory for binarize sum(如下图),请问我要用这两个输出文件分别是什么意思,我要下一步进行统计计算用哪个文件夹。
下面是我分别用binarize和weighted进行单样本T检验的结果,感觉稍微有些不一样,请严老师指导,谢谢。

error using dparsf

Hello
I used Dparsf for resting state fmri images, everything was done according to the manaul, but i receive this error again and again, how can i solve it

??? Error using ==> parallel_function at 598

请教一个关于mask的问题

 尊敬的各位老师:

can xjview be used for rehomap

hi
after performing reho analysis, can the rehomap image be used for viewing in xjview.
xjview is used for viewing t-maps (thresholded t-maps) of spm

I have a image file which is the result of a Reho analysis. I want to make a mask of the activated region. How can I do it?

I want to make mask of activated regions or of unactivated regions from the rehomap.
how can i further proceed

no result after performing one sample t-test for the mrehomap

hi
i got two rehomap after performing reho analysis. after that i used the mreho map for statistical analysis.
there was no error and t-test was completed sucessfully, but when i overlayed it on ch2 template image. it was just a blank image(like plain colour)

How to create clusters of activated regions for resting state fmri

Rehomap was created and overlayed over an ch2 template, now i want find the clusters having hypometabolism or in different contrast.
can i use xjview for that, can rehomap be used?
