Hi there ...

I'm afraid I'm stumped. I don't see the connection between Powershell and py4cytoscape, and I don't recognize anything in the key/value you've provided.

py4cytoscape is a Python package that isn't directly executable by Powershell, and I have to admit that I've never executed py4cytoscape either directly or indirectly via Powershell.

Can you give more context and detail??

Thanks!
