SPM fMRI结果显示时遇到了问题?

严老师:
我有个问题请教,还请您春节里抽空给予解答:单样本t检验、参数估计都很好,但结果显示时,选中FDR校正之后问P=0.05点回车确定,没有&extent threshold选项就直接蹦出下面的结果。
 

并且MATLAB command window里提示:
========================================================================
contrast image  1               :        ...written con_0001.img

No valid image in '.../PicturesForChkNormalization'

Hi,

Recently, I have run 3 times ReHo analyses on healthy controls and patients. Two of them did not show any valid images in '.../PicturesForChkNormalization' but one analysis using patients' data had valid images. Does it mean any errors during the DPARSF process? Thank you very much in advance! If there is anything I can do to solve it out, please feel free to contact me!

Happy Spring Festival! All the best!

REST-GCA

Based on Resting State fMRI Data Analysis Toolkit (REST), we implemented GCA on MATLAB as a graphical user interface (GUI) toolkit. This toolkit, namely REST-GCA (as a component of REST), could output both the F on residual and the signed-path coefficient. REST-GCA also intergrates a programme that could transform the distribution of F on the residual to normal distribution and then permit parametric statistical inference at group level.

Please see the attachments for detailed discription and usage of REST-GCA.

求助……

严老师,
    我在分析是先后遇到了2个问题,实在做不下去了,向您请教?
    1、Slice timing中,我输入的TR=2s,但是当Slice timing结束,MATLAB command window却提示TR=0.4s,奇怪,这是什么意思?
    2、我在用REST提取协变量的时候跳出“Undefined function or method 'exist' for input arguments of type 'cell'.”的对话框,做不了,MALABcommand window 里提示
Exception occured. (MATLAB:UndefinedFunction)
Undefined function or method 'exist' for input arguments of type 'cell'.

计算ReHo时给出的错误。

我注意到我的 DPARSF 在计算 ReHo 的时候,在 Matlab 的命令窗口给出了这样的信息:

Read these 3D EPI functional images.    wait...

erro messages when extracting ROI times series and functional connectivity

Hi:

I used DPARSF for extracting ROI time series and functional connectivity on previously precprocessed data.
My data are 53x63x46, so I've reslice mask with Coreg-Reslice under SPM as the video mentioned.
But error messages showed that wrong mask dimension was noted.
Moreover, these error messages remained even I chose "null mask" item.
Could someone tell me how to fix this problem?
(I've pasted the messages below)

Thanks

??? Error using ==> rest_loadmask at 64

How can I get the average Z score after group analysis ?

Hi!
     I have done the functional connectivity sucessfully,but How can I get the average Z scores and standard deviation of the clusters after group analysis ? Rest slice can just report the t value. Thanks!

测试数据

对于Resting这个软件有想SPM一样的测试数据吗?这样我们就可以检查自己做的是否正确了。

problem with DPARSF

 

HI!
     thank you for your reply on functional connectivity. Today I want to process the resting state fMRI data with DPARSF.After I arrange the sub_001、sub_002… in the FunRaw folder,I run the  DPARSF,the mistakes come as following:
