Error using tlstsq

Hi,

I repeatedly encounter an error, irrespective of measure, binary or weighted measures, and irrespective whether graph metrics are normalized with random networks. I attach the workspace I would prefer to use as well as the error code. :)

I would be very grateful for any help! :)

I am using MATLAB R2019a, we are calculating with 211 subjects. Here, I only selected 11 ROIs and 11 thresholds.

Thank you very much!

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

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.

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:

同一台机器参数不一样 还能放在一起预处理吗

各位老师好,

我们最近有一批数据,用的Phillips 3.0T的磁共振扫描的,但是在扫描过程中发现机器的参数发生了改变。一部分静息态数据slices是33层,另一部分则为35层。想问一下老师们,这两批数据可以放在一起用DPABI预处理和分析吗?

谢谢各位老师!

DPABIsurf 安装报错

Submitted by yubing on

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!
