GMN dataset modify

Hi author:

In your original code, the new graph is obtained by modifying the original graph. If I want to use GMN to compare existing data sets, how should I modify the code?

I have a 1003*2 dataset, each row represents one individual, so there are 1003 individuals. The two columns in a row represent the fMRI data (which can be seen as a graph of brain functional connectome) of the same individual in two different days, and each fmri data is a 300*300 matrix. I want to use GMN to identify individuals by comparing the graphs in the first column and the graphs in the second column (just like a fingerprinting problem).

Thank you!
