In Marsbar you can extract the data for the ROIs using the Extract
data menu option. You could choose all your ROis at the same time to
extract the data in a single step. Then you can save the resulting
time courses to a mat file or put the time course data into the
workspace using the export options. Once you have the data as a .mat
file or matrix in the workspace, you can use MATLAB corrcoef to make
the correlation matrix,
