REST-GCA

Submitted by zangzx on Thu, 02/04/2010 - 17:12

Based on Resting State fMRI Data Analysis Toolkit (REST), we implemented GCA on MATLAB as a graphical user interface (GUI) toolkit. This toolkit, namely REST-GCA (as a component of REST), could output both the F on residual and the signed-path coefficient. REST-GCA also intergrates a programme that could transform the distribution of F on the residual to normal distribution and then permit parametric statistical inference at group level.

Please see the attachments for detailed discription and usage of REST-GCA.

严老师，
    我在分析是先后遇到了2个问题，实在做不下去了，向您请教？
    1、Slice timing中，我输入的TR=2s，但是当Slice timing结束，MATLAB command window却提示TR=0.4s，奇怪，这是什么意思？
    2、我在用REST提取协变量的时候跳出“Undefined function or method 'exist' for input arguments of type 'cell'.”的对话框，做不了，MALABcommand window 里提示
Exception occured. (MATLAB:UndefinedFunction)
Undefined function or method 'exist' for input arguments of type 'cell'.
