Dear Mr. Yan:

I defined 56 ROIs and get 56 functional connectivity graphs across all subjects by REST. Now I’d like to compare every two graphs so as to find out the similarity of them, that is to get the r values between the two graph. I use the Image Calculator to finish this work, but I have to repeat the same manipulation 56*55/2 times.

Dear Chao-Gan

Hello
Thank you so much for your time. I have read your paper on  GCA and  need your help. After obtaining the path coefficients how could I perform a one sample ttest since I do not know the population mean?
Secondly, what is used to represent the connection strength between areas? t value of the related path coefficients?

Many thanks,
mahsa

老师们，

圣诞节快乐！

我的一篇文章大修，由于本人水平有限，有个地方理解不了，特此请教：

1.我的静息态数据预处理，完成：时间校正；头动校正；之后回归nuisance covariates (linear trends, Friston 24, and WM & CSF），之后，将Mean FD（Jenkinson）超出mean FD +2SD的被试删除了。----之后再进行后续空间标准，smooth, fALFF等计算;之后将mean fALFF与行为数据进行协相关分析（以每名被试的mean FD(Jenkinson), gender, age为协变量），

Hi,

I am trying to run a correlation analysis using the Statistical Analysis tool.   However, I'm getting the error as below.  Also, do I need to demean the data prior to doing the correlational analysis, or does DPABI do it for me?

Thanks,

Matt

Dear experts,

I encountered following error message when running resting state data of 80 subjects on windows 7 64 bit with 16GB memory. The process was about 80% completed.

Your help is very much appreciated,

Hello, I am wondering whether DPARSF's realign parameter the same as SPM default parameter or not. 

Your help will be greatly appreciated!
