How do I change the tech tree?

[gutza1]

I'm using MissionControllerExtended, and I want to change the tech tree to start with probes and a science part. I looked in the KSP files but I didn't see any config with the tech tree node definitions. Is there any way to change the tech tree without waiting for MuMech's TreeEditor?

The actual tech node for parts is defined in the part.cfg file....so if you want to move parts around on the nodes, but not change the nodes themselves, it's a simple text edit.
