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.

Thank you for using REST!
