Dear DPARSF experts,
whilie running DPARSF I have encontered the following error reported in DPARSF_run.m:
Error using ==> copyfile
No matching files were found.
Error in ==> DPARSF_run at 551
copyfile('*.ps',['..',filesep,'RealignParameter',filesep]);
老师，您好：
请教一个问题，我有病人组16个被试，利用DPARSF计算其ALFF值，然后利用单样本T检验得到病人组内ALFF显著高于全脑均值的区域A,B,C
问题：如果我想单独得到被试甲的ALFF显著高于全脑均值的区域在哪里，我需要用什么方法，什么检验？刚才我单独利用被试甲或被试乙的mALFF分别做了一个单样本T检验，之后用REST slice viewer发现什么结果都没有。是否是单样本T检验要求纳入被试人数需要大于3个的原因？
盼回答，谢谢！！
Dear authors
Just a quick (and silly) question wrt Slice Viewer.
I'm wondering whether the P value in the control panel represents corrected or uncorrected for multiple comparisons?
Thank you in advance for your kindness.

hello
I am new to fmri analysis and am very much keen to carry forward my career in this field and would be really glad to know where i could download fmri data for research purpose.could anyone please suggest sites or links where i could dowload fmri data
thank you

老师：
你好，我使用rest提供的mask来提取全脑、CSF、白质的信号，但是我发现这些mask的中心点坐标即origin coordinate是0，而SPM里面的图像则不是。所以无论使用MRIcro的overlay还是SPM的checkreg功能，rest提供的mask与SPM里面的图像都不配，这样的话是否提取mask内的信号是可靠有效的呢？因为我不知道其计算的原理，所以在此发问，我的图像都已经是重采样后与mask相同的体素大小和坐标框。
请老师解释一下。

在dparsf中假如用4个ROI做功能连接，如A,B,C,D，生成的结果为ROI1，ROI2，ROI3，ROI4，请问，这里ROI1-4与A-D的对应原则是什么？是仅仅按加入时的顺序还是按ASCII的大小排序，请明示？
在计算激活体积的尝试中，例如mPFC,但是我不知道mPFC这一脑区通用的mask的大小（体积范围从多少到到多少）或者是x,y,z,MNI坐标的区间范围？
还有就是：请问如何得到mPFC的mask图像 。
谢谢了。
Dear REST developers and experts
To the first, I really appreciate for providing a wonderful free software.
I've also attached the following query to the SPM mailing list.
I'm analysing seed-based (hippocampus) resting-state functional connectivity between patient and control groups by using spm8 and especially REST program.
The resulting zFC maps of include both positive and negative correlations.
Dear REST experts,
Thank you for your excellent software REST and DPARSF.
I'm interested in Granger Causality Analysis (GCA). I think that shorter TR is recommenced when we try to do GCA. When we use REST GCA tool, how long TR will it be recommended?
Thank you in advance,
运行REST 的计算机硬件配置应该是多少？麻烦诸位专家指教，多谢
