problems with "Single-level example"

[Juan]

Hi, List experts,

I am not sure what reason why I can not run the example meditation below. Any good pointers?

Thanks so much,

Juan

Hi Juan, 

Do you have CanlabCore tools in your path? https://github.com/canlab/CanlabCore

To use mediation analysis, you will need CanlabCore tools. 

Thanks,

Wani
