Hello, I´m very new in Rest, I have only one Patient and I want to see the activation areas in resting state, I already got the ALFF, fALFF and Reho, and I tried with the Slice Viewer, but when I choose the T1 image for the overlay, the next message appears: This NIfTI image includes an rotation transformation. You should reslice this data before attempting to overlay the image,

严老师： 您好！我在进行slice timing 时出现故障，提示如下： The following modules did not run: Failed: Slice Timing ??? Error using ==> cfg_util>local_runcj at 1426 Job execution failed. The full log of this run can be found in MATLAB command window, starting with the lines (look for the line showing the exact #job as displayed in this error message) ------------------ Running job #1

严老师： 您好。我以PCC为种子点得到了正常组跟病例组的FC值，用zFC分别做了单样本T检验和双样本的T检验。正常组与PCC相关的脑区与文献相同，病例组得到的相关脑区要少于正常组，但是做了双样本T检验之后发现，病例组在单样本T检验没有出现激活的脑区，现在出现了激活，正值负值都有。例如海马旁回和枕叶，单样本的病例组并未出现任何激活区，但是做完双样本时候海马旁回出现了负值，而枕叶却出现了正值。请问这是什么原因呢？是不是我的数据有问题？该如何分析这种情况？谢谢。

在Kevin Murphy（The impact of global signal regression on resting state correlations: Are anti-correlated networks introduced?）一文中：global signal regression is used as a regressor in a general linear model (GLM) to remove the associated variance.This technique assumes

严老师： 您好，我做了REHO的双样本t检验，结果如下：
为什么会有激活区跑到脑外去？是我采样的问题还是处理过程中出了问题？单样本T检验的激活区都是在脑内，而且做的ALFF的值也都是在脑内，唯独REHO的双样本T检验出现了这种情况。希望能得到您的帮助。

1. Should I use smReHO - 1 or just smReHO for a paired t-test? 2. In ExcludeSubjects.txt what is the default or recommended criteria for excluding subjects? 3. Which of the DPARSFA choices does NOT effect ReHo analysis? For example, if I check "smooth" will it smooth the data before ReHo or does "smooth" only apply to fALFF, ALFF, and FC analysis?

Dear REST experts, I encounter the same problem with `Results may be inaccurate. RCOND = 1.034803e-027` which was posted at Thu, 02/17/2011. I was not able to find the answer in the forum about that. Would you mind explaining how can I solve this problem? Thank you in advance. Yours sincerely, Yuki Sakai

Hi again, When I try to run the analysis on REST using the functional connectivity tab, I get the following error message. Does anyone know what indices the message is referring to? My header and img files have this label: 20101118_1621541BlankCTRLs003a001_120.img (or hdr). Thank you very much. Yoon-Hee Exception occured. (MATLAB:badsubscript)
