Any questions you encountered with this site could be posted as a comment to this topic.
Please feel free to explore this researching site. I hope it be a start point of your resting-state fMRI research interest.

One advice is reading “How To Ask Questions The Smart Way”. And another advice may seem on the contrary: never hesitate to question yourself and then question in resting-state fMRI forum.

Parametric test with GCA output

Dear REST experts,

Thanks for your recent works, REST-GCA :)
I am trying to perform granger causality analysis using REST-GCA. I conducted both coefficient-based and residual-based GCA for controls group and patients group and got several outputs for each group. These outputs were finally transformed into Z-value. Now, I'd like to perform between-group comparison using parametric test (i.e., two sample t-test). However, I am not sure what output files I use to do this.
(1) Is it right that two outputs ("GCA_x2y_1" and "GCA_y2x_1", which are not z-transformed values) for coefficient-based GCA are used to perform between-group comparison?
(2) Is it right that four outputs ("GCA_x2y_Transformed", "GCA_y2x_Transformed", "ZGCA_x2y_Transformed", and "ZGCA_y2x_Transformed") for residual-based GCA are used to compare both groups?

Please comments.
Thank you in advance.

请问一下用Dparsf选了DICOM to Nifiti以后，出现这个错误，是不是与原数据文件有关呢？

我用的是matlab2009a的版本，原数据是用西门子设备采集的，它的文件是没有扩展名的
??? Undefined function or method 'spm' for input arguments of type 'char'.

Error in ==> DPARSF_run at 120
[SPMversion,c]=spm('Ver');

Error in ==> DPARSF>pushbuttonRun_Callback at 939
[Error]=DPARSF_run(handles.Cfg);

Error in ==> gui_mainfcn at 96

Error in ==> DPARSF at 41
gui_mainfcn(gui_State, varargin{:});

??? Error while evaluating uicontrol Callback
谢谢！

Cool Cumulus Cloudy Tags support!

I added cumulus tags to this site. It spent me 1 days or so. But one look at the effect make me proud of it. It deserved.

I hope it would help you too.
