严老师好！

    我在处理fRMI数据的时候，通过ReHo和fALFF计算得到显著的区域，打算将其作为ROI进行功能连接分析。

但我不是很明白functional connectivity和ROI time courses的区别。按照视频中的内容，FC是voxel-wise seed based的相关分析，

而ROI time courses是ROI-wise的功能连接分析，则应该选择ROI time courses才对。但这样说的话，FC又是在什么情况下才使用呢？

    另外就是在使用两种方法之后，发现ROI time courses中提取时间序列的数值，就是对应的种子点的均值，这个是可以理解的；而FC得到的

SeedSeries则不是简单的均值（虽然数值上很接近，但确定是不一样的）。关于这个问题，实际上严老师17年就在

严老师好，各位老师好，最近用dpabi做Dynamic Analyses，然后结果文件夹里面每个指标的结果都有3种前缀，分别是CV，Mean和Std，想咨询一下这3种前缀的结果文件分别是什么意思，我应该用哪个结果进行组间差异的统计分析呢？

Hi, Dr. Yan, 

While I used the DPABI_Utilities to extract values from the preprocessed images (gifti/nifti), an error as following occured. I tried to debug including: 1) change the version of dpabi; 2)  runs on other computers; 3) change the other atlas; 4) re-set matlab path, however, the error still occured.

For nifti data:

Hi, Dr. Yan, 

In these 2 days I've encountered several problems using DPARSF 5.2, expecially with the Preprocessing for Task fMRI data, and I'd like to ask you some suggestions to fix the anomalies. In particular, the error starts when I try to open the window to set up the preprocessing, it crashes immediately, showing in the command window these errors:

"Operands to the logical and (&&) and or (||) operators must be convertible to logical scalar values.

Dear Experts,

First, thank you so much for sharning this dataset.

I have downloaded the "REST-meta-MDD-Phase1-Sharing.zip" data and I am interested in using the preprocessed fMRI time series.

Hi, Dr. Yan,

When I run the subjects in DPABISurf, there are two subjects cannot be processed at the fmriprep while others can? Could you please have a look and give me some suggestions on how to deal with it? Attached please find the error info and the file. Thank you for your expended time in advance!

==========================================

Dear DPABI team,

I try to create the 90% EPI coverage mask using the respective function in quality control. I preprocessed the data using DPABIsurf pipeline and fMRIprep. 

I keep getting the error message 

Reading images from "/Users/julian/Documents/Research/DPABI_Surf_neworder/Masks/AutoMasks/wAutoMask_Sub_001.nii" etc.

Error using y_Read (line 54)
