Dear REST experts,
i have performed the preprocessing of my rest fMRI data followed by the ReHo processing. after running the analysis, i have the rest ReHo*.* image, but this image is empty, can anyone suggest me where could i have made mistake (preprocessed image - smmothed image is looking fine)
Hi, I have been using DPARSFA for preprocessing and it has been working very well so far. I tried to remove the Global Signal nuisance regressor, but after doing so my data has no voxels left -- i.e., when I enter it into a first-level model in SPM, and estimate the model, I get this popup message:
-----
No inmask voxels - empty analysis!

各位老师好！最近在处理一批病人的数据，头动较大（放宽至3mm和3°）的被试比较多，但是被试的总体数量又比较少。想请问一下各位老师有没有对头动的被试的处理的方法。
暂时有两个想法：1.去掉头动较大的时间点。2.不去头动的被试，最后将头动作为协变量去掉。暂时只是这样想，还没有找到文献的依据，不知道具体可不可行，还请老师指点，多谢！
Hi, admistrator
first, above all, thank you for providing your program
Our researchers have studied ADHD adolescent and their brain activity used in fMRI.
Our study is block design and I have analysed this by using SPM8.
严老师，我在用dparsf时有warning和报错如下，请您指导一下是哪块出了问题

Dear Dr. Yan,
I have read your recent paper in Neuroimage about head motion, very informative. I have serveral questions:
1)The whiskers bar figures present your results very clear. It looks better than the traditional whiskers bar.
我想问一下 我用DPARSF做静息的数据 会出现这样的警告
但是程序依然会继续进行 是怎么回事啊
Hello,
just a general Functional Connectivity / ROI question: is there something like a "minimum size" required for a ROI to perform valid statistics? Would like to know your opinion on that.
Best,
K
Dear DPARSF team,
I have analysed my resting state data with two different approaches:
1. using the DPARSF toolbox
2. using in house scripts for Matlab/SPM.
Interestingly the results are fairly the same expect that the t-values on group level are much higher in DPARSF (FWE .05 k10, tmax= 104,67,
(seed 51, 12, -27)) than for SPM (FWE .05 k10, tmax=63.08, (seed 51, 12, -27)).
Warning: Escape sequence 'Z' is not valid. See 'help sprintf' for valid
escape sequences.
