I can not find the 'predict_behavior.m' script

Thank you for providing the useful code.  I'm trying to reproduce the code form the paper 'Using connectome-based predictive modeling to predict individual behavior from brain connectivity' , but I cannot find the 'predict_behavior.m' script mentioned in the 'calculate the true predict correlation'part. Could you guide me where it is? Thank you again.

Kind regards,
