How to Configure System Variables

Hi everyone,
I am trying to use RxD mechanism. Python is installed but NEURON can't connect to it (likely a path issue) . I am trying to find a document or video to fix that problem but I could not. Can anyone help me please how to configure system variables ?

RxD in Neuron

Hi

I am trying to use rxd and find the na, k concentration using NEURON, but I read many web talking how to use rxd in Python. can any one guide me to use RXD in NEURON itself. thank you.

Best Method

hi everyone I am trying to solve the cable equation with set of concentration equations for Na, K and Ca. I read a discussion for solving a such system and someone said that the value of concentration was small and Ted told him to change the way of solution because that used way kill the concentrati...
