Hi DPARSFer,
We used to use DPARSF_V2.3 to process rsfMRI data three years ago. When I set path "Working Directory", no participant is listed (showing) in "Participants". I have tried to set up a folder - "FunImg/Subject001/.img/nii or a folder - "FunRaw/Subject001/.dicom". What did I do wrong? Any advice would be greatly appreciated.
Best regards,

尊敬的各位老师，
在用Dpabi做数据预处理时我们常用默认推荐的DARTEL做分割，然后配准到标准空间。但在了解一些DARTEL的知识后有了一个困惑：我所理解DARTEL是根据处理组中所有人的信息生成了specific template，然后基于这些template做配准。这样的活，如果我想在加入新的被试，那么我应该是将这个被试和之前已经处理的所有被试放在一组再重新处理一遍？毕竟上次处理DARTEL生成的specific template 并没有包含这个新来的被试信息。还是说只要将这个被试一个人重新做个预处理？这两种做法会有很大差异么？比如我想做个多站点的数据处理，由于不同站点的采集参数不同，我可能会将站点分开处理，这样应该每个站点都有自己的specific template，会对配准或分割有影响么？或者将分割前分站点处理，后面分割、配准到标准空间时再将所有站点放在一起处理？
可能我对DARTEL的理解有错误，望老师们指正。
老师，您好！我用dpabi做ANOVA，生成结果F.nii想做GRF校正报错，请问是什么原因呢？用FDR和AlphaSim校正都可以正常运行。
Dear all,
Recently, I met some problems when I used Dpabi for fMRI data preprocessing .
1) Usually,after normalization, error "Function 'subsindex' is not defined for values of class 'matlab.ui.Figure'." will be reported in matlab so that we couln't obtain PicturesForChkNormalization files. Our version of matlab is 2017b in Ubuntu 16.04, how do we work out this problem? Or what's recommend version of matlab?
Dear DPABI users
Would it possible to generate a QA report for ROI outlines overlay on the top of functional & strcutral images in MNI space?
Thanks for considering my request.
Best wishes

Dear Prof. Yan,
The TDA module was performed to calculate the concordance (the dynamic metrics was calculated before, e.g. the alff+falff, reho, DC and GSCorr ) and the error information was as follows,

Dear all,
I want to use the data preprocessed to do the later analysis such as build a martix. But some subjects has limited timeseries when I finished scrubbing,which may result in a strange result. So I want to know how many time timeseries left in a subject( for my case ,the total time series are 180,first 5 were revoved at the very beginning part) is enough for further analysis.
Sincerely,
Lin
