Thanks for your excellent work, I learned a lot from you paper.
I successfully reproduced the state machine inference process of RAT.However, I encountered some errors when reproducing the other options.

when run ./run.sh examples.smtp.smtp_client_inference, It runs for a while and then outputs the following message

I really hope to have further communication with you.
