脑网络节点属性统计分析

Hi,

麻烦问一下,在对节点分析进行统计时,比如组间比较,我们很难像分析全脑属性一样把具不同sparcity的网络都分析一遍,因此都是取的某一个范围内网络节点属性的均值对吗?如果是的话,哪一个范围更为合适呢?或者有无研究专门探讨过这个问题的呢?非常感谢~~~

DPARSF Error/Bug Report Parallel Pool

Hi All,

I just wanted to share my experience about an error I got in DPARSF in case anyone else comes across it or in case the DPARSF creators want to fix this in future versions.

I have been running DPARSF jobs and they seem to fail a portion of the time somewhere after the initiation of the BET step.

Before this step, DPARSF requires user input (in my batch at least) saying "No co* images found" or something along those lines.

Start DPARSFA from NIFTI images

To whom it may concern,

I would like to start preprocessing in DPARSFA from Nifti images so I placed the images under the FunImg folder (which contains a folder for each subject). However, when I change the 'Starting Directory Name' to FunImg. I get the following warning: 'Please arrange each subject's DICOM images in one directory and then put them in FunRaw directory under the working directory' and the gui automatically revert to FunRaw (which I do not have as I want to start from nifti images).

Could you please advise how to solve this problem?

Thank you,

Between group FC

Dear Yan,

Although I am still learning, I am very happy with your software for the resting state analyses.

However, I have a doubt. I performed the FC analyes considering the ROI1. Then, I used SPM to compare two groups G1 and G2. At the whole brain, I obtain a significative difference between the two groups in the cluster C1.

perform Friston motion regression

严老师:

您好!

我想用您的DPARSF-A toolbox来做Friston motion regression,只需要做这一步,我的数据格式为.nii.gz,我将每个人的数据分别放在一个文件夹 ,并将它们全部放在FunImgARWSDF下面,在DPARSF-A 的界面上仅仅勾选Friston24,其他都不勾选。但是报错为

Difference between time series extracted by "Functional Connectivity" analysis and "Extract ROI Time Courses"

In DPARSF, "Extract ROI time courses" can extract the ROI time courses from the defined ROIs, as stored in: ROISignals in {WorkingDir}/Results/ROISignals_FunImgARCWF/ROISignals_Sub_001.mat

"Functional Connectivity" analysis can also extract the ROI time courses, as stored in: SeedSeries in {WorkingDir}/Results/FC_FunImgARCWF/ROI_FCMap_Sub_001.mat

关於FC分析

您好,
 
我是DPABI的新使用者,关於FC跑完後的结果,想确认我的理解是否正确。
 
每个参与者有170个TR,一共设置了6个ROI,并勾选了Functional Connectivity以及Extract ROI time courses
 
最後我在Result资料夹得到了FC_FunImgARCFWS, ROISignals_FunImgARCFWS, VMHC_FunImgARCFWSsym三个资料夹
 
我想我要的资料应该在FC_FunImgARCFWS与ROISignals_FunImgARCFWS两个资料夹内
 
FC_FunImgARCFWS内有以下档案:
 
ROI_FCMap_XXX.mat: 读取後在workspace得到名为SeedSeries的variable,为170(TR数) x 6 (ROI数)的矩阵。看起来应该是该ROI的time course?
