关于提取ROI时间序列的疑问

Submitted by lizhe8785 on

老师们,您好!

1、我想确认一下我这样做是否得到正确的功能连接矩阵:我用DPABI做完预处理,对“FunImgARWSDFCB”文件夹exact ROI time courses,以aal为mask,得到的ROICorrelation_***.txt就是功能连接矩阵吗?是不是可以将此txt文件放入GRETNA-Network Analysis做拓扑属性分析了?

2、我用aal为mask提取ROI时间序列,“ROICorrelation_***.txt”显示为116*116的矩阵;但用Power264作为mask,所有被试的“ROICorrelation_***.txt”只显示一个 1.0000000000000000e+00 ,请问是什么原因呢?

万谢!

analyzing output from xcpengine

Submitted by Danella on

Hi Chao-Gan,

I am conducting analyses using fmriprep and xcpengine, and I would like to use DPARSF to extract ROI time courses and compute seed-based functional connectivity. When I enter the fully preprocessed images into DPABI, I encounter the following error. Do you have any ideas about what I might try? Thanks!

Best,

Danella

Dear Chaogan 

I am a new user of the toolbox. When I try to run the code, I got the following error during coregistering. Could you help me out. I have double check the original files in FunImg (3D hdr nii images) and T1Img. By the way, I am Mac system user. 

Thanks for your time. 

Best

dpabi中数据预处理后的问题及BrainNet Viewer问题

Submitted by songmian on

老师,您好!我在dpabi使用过程中遇到两个问题,希望得到解答:

1、我们现有一批预处理过的数据,文件名为“FunImgARWDCFB”的“.nii”格式文件,请问1)这些数据是不是不能用于计算fALFF,而其他指标可以被计算;2)由于没有结构项的数据,是否无法得到“灰质密度”和“头动校正Mean FD值”的数据以作为统计分析时的协变量。

2、通过dpabi中的Viewer试图打开BrainNet Viewer时,出现报错如下:

各位专家:

您好,我的运行环境是 Win10 专业版 (补丁1809),Matlab 2011

我按照安装教程,首先安装了 Docker Desktop  community 2.0.3 (Engine 18.09.2,Machine 0.16.1),然后下载并解压了 dpabi41docker 文件(解压后18.4G),在 load local docker 时,加载了 repositories 文件,出错显示

Error processing tar file(exit status 1): unexpected EOF

不知道问题出在哪里,麻烦指教,谢谢!

SPM pre-processed data DPARSFA ReHo,ALFF,fALFF

Submitted by trabz on

Hi experts,

 

      I want to compute ALFF , ReHo and fALFF from SPM pre-processed (realigned,coregistered,normalized,smoothed,segmented) data. But when I try to do that analysis it throws normalizing error at DPARSFA step. It has produced fALFF,ALFF and ReHo even FC then after it has failed at normalize (Tried with EPI templates, T1, Dartel ). Here is my problem ; Result sets of this analyses are not fitting with anatomical sets why is that happening ?  How can I fix that ? 

 

Thanks

Abdullah
