DPARSF4.3(DPABI)预处理报错

严老师您好,我在用DPARSF4.3(DPABI)进行猴子数据预处理时出现报错。已经生成了T1ImgSegment文件夹,准备生成T1ImgSegmentCovs文件夹时(即已经完成分割后准备进行协变量去除时报错。报错如下,望您指正:

Temporal Dynamic Analysis

Dear DPABI community,

I have some questions regarding temporal dynamic analysis. I have two groups of subjects, AD patients and healthy controls. I want to compare the patterns of dynamic r-fMRI indices and and their concordance.

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

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

Failed 'Coregister: Estimate' Index exceeds matrix dimensions.

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
