Dear Expert,
I am running rs-fMRI demo data provided on your website for 3 subjects on DPARSF V2.1 for ALFF and ReHo calculation. I preprocessed data till smoothing on SPM12 running on Matlab R2016a. After preprocessing I put all the data in FunImgNormalizedSmoothed folder. For detrending and filtering when I use DPARSF V2.1, I am getting an error for timepoints (screenshot attached).
Any help would be appreciated.

Dear Experts,
I re-ran 2 subjects through DPABI using the same parameters and ROIs that I used for the same two people that I ran as part of a larger group ( n=50).
When I compare the output folders FunImgARCFWS_ROISIGNALS/ROISIGNALS_subjectx of the same person, the ROI time courses look very different, even though I used the same parameters as before.
Would you know why that is? I can only imaging that in my prior analysis these two subjects were run as part of a different group? Does the ROISignals .text output gets normalized according to the included subjects?

严老师好，
我这用dpabi做FC与行为学的相关的时候出现了如下报错，应该如何处理？
我使用的dpabi版本是V3.1， MATLAB2017，WINDOWS 系统。

Dear Chaogan,
I have a problem during doing data preprocessing using dpabi. The data is okay at the files under FunImgR (the first image below). However, it became pixelized starting from FunImgRC (the second image). Any idea of what could have gong wrong? Thanks.

严老师，您好！
最近使用DPARSF做功能连接的分析，审稿人提出了一个问题如下：
5． The author should check and calculated the head motion issue (such as FD and DVARS), otherwise, how to control the head motion issue, even authors had applied regression of nuisance covariates.
我想问一下，这个FD应该用哪一个作为指标：FD_Jenkinson\FD_Power\FD_VanDijk，txt文件中的量纲是不是mm呢，以及排除标准。以及DVARS在软件中有没有计算，在哪里；如果没有计算，我该如何计算呢，非常感谢方便时候能够解答一下！

dear DPABI team, i need your help to know how to define ROI for prefrontal brain cortex?
2nd question how to get values of ALFF for each individual , i attached ALFFmap of one individual?
with my regrads,

Dear R-fMRI Network team,
I am looking at the ROI Signals_ xxx which outputs the time courses for each ROI and I am surprised that some of these numbers are negative? Could you please explain why that would be the case?
With kind regards,
Catherine
