How to check the positive predicted edge and negative predicted edge

Dear all,

Recently, I have run the code "[y_predict, performance] = cpm_main(x,y,'pthresh',0.01,'kfolds',10)" and I got some results. However, when I want to visulize what brain node made the contribution to the prediction, I can not find the edge files which could help me to map to the brain. Can any one kindly give me some suggestion?

Best,
